techBASIC 2.3 Release Notes

New Features

1. •Write programs to access Bluetooth LE devices. Program the Internet of Things right from your iOS device!
   

2. •techBASIC now supports both vector and pixel graphics drawing modes. Use vector graphics when the image will be scaled or shared, and pixel graphics when drawing repeatedly to the graphics screen.
   

3. •Drawing commands are now available in the Image class. Draw on top of existing images, or create images entirely from scratch, then use them for buttons or to blit to the screen.
   

4. •Turn antialiasing on or off.
   

5. •Draw images to the graphics screen using the new drawImage command.
   

6. •setColor now has an optional alpha value, allowing drawing with translucent colors.
   

7. •New trig functions include ACOS, ANGLE (two-argument arc tangent), ASIN, COSH, COT, CSC, SEC, SINH and TANH--everything you'll find in most trig classes is now in techBASIC.
   

8. •New trig helper functions include PI, DEG and RAD.
   

9. •Logarithms are available for base 10 and base 2.
   

10. •The MOD operator returns the integer remainder from a division.
    

11. •PRINT and PRINT USING can now print to strings, making it easy to take advantage of the formatting power of PRINT USING.
    

12. •The POS string search function allows fast searches within BASIC strings.
    

13. •The new LTRIM and RTRIM functions make it easy to remove leading and trailing spaces from strings.
    

Bug Fixes and Minor Changes

1. •Help is now indexed, so you can find help in the long list of functions, statements, classes and methods quicker.
   

2. •It's now possible to edit at an error location without moving the cursor from outside the error: Tap on the selected error area, and the error disappears and you begin editing at the tap location. As before, tapping on an error other than the one with a visible message displays the error message for that error.
   

3. •Sharing text with the Share button no longer leaves techBASIC. The email message that is generated still uses Mail for distribution but this is done from within techBASIC.
   

4. •MOD is now a reserved word. POS is no longer a reserved word.
   

5. •The SIZE and LBOUND functions failed on passed parameters. They work correctly, now.
   

6. •Math.zero could fail to find an answer in some situations. Adjusting the search range returned a valid result. It works correctly in these situations, now.
   

7. •Disabled and hidden controls still reported touchUpInside events. This no longer happens.
   

8. •When sharing source code using the Share button, leading spaces are now properly preserved.
   

9. •Corrected the parameter name for the URL parameter in the documentation for the finishedLoad event.

techBASIC 2.1 Release Notes

New Features

1. •The LCASE and UCASE functions make it easier to convert strings to uppercase or lowercase.
   

Bug Fixes and Minor Changes

1. •Several interrelated issues were found with the debugger and source editor. These generally occurred upon leaving techBASIC and returning to it, especially if a program was being debugged at the time. Symptoms included vanishing line indicators in the debugger, hangs, crashes, and source changes being lost. All known issues have been corrected in 2.1.
   

2. •On the iPad in portrait view, swiping showed the program list, interfering with using plots and controls. Swipes no longer show or hide the program list.
   

3. •On page 70 of the manual, the toUpper sample uses a + to concatenate strings. This is incorrect; the & operation is used to concatenate strings.
   

4. •Functions were not able to return objects; they can in 2.1.
   

5. •On the iPad in portrait view, the program list stayed visible after selecting or running a program; now it is hidden.
   

6. •The icon bar icons on the iPad were still displayed in standard resolution on retina displays.
   

7. •BASIC programs ported from Windows that used the Latin extended character set would not load, and generated multiple errors to let you know they would not load. Files that cannot load now display a single error message, and files using Windows Latin characters now load in techBASIC.

techBASIC 2.1.1 Release Notes

Bug Fixes and Minor Changes

1. •techBASIC 2.1 fails to run on iOS 5. This is due to an iOS 5.1-only call made during initialization. This has been corrected in 2.1.1.
   

2. •techBASIC frequently hangs when programs are paused, to include both the pause button and hitting a breakpoint. This has been corrected in 2.1.1.
   

3. •Errors reported when a non-existent method name was used appeared a few tokens after the actual use. The error message is correct and appropriate, it’s just in the wrong place. The error now appears on the class variable.
   

4. •The help file says the range of values for Date.month is 0..11. This has been corrected to read 1..12.
   

5. •PRINT USING fails on some format specifiers, such as PRINT USING “##,###”; 32767. These work correctly, now.
   

6. •Running on an iPad in portrait mode, running or editing a program hides the program list if the program is not currently selected, but does not hide the program list if the currently selected program is edited or executed. The program list now hides for all program executions or edits.
   

7. •Running on an iPad in portrait mode, opening the program list always selected the first program. It now leaves the previously selected program selected.

We want to hear from you, both about any problems you have and about your successes.

Bugs happen. We’d like to be perfect, but we know we’re not. If you find a problem, please tell us. As our long-time customers know, we’ll do everything we can to make it right.

Tell us about what you want to see in future versions of techBASIC, too. The major input when choosing new features is what our customers are asking for, so don’t be shy about telling us what you want to see!

techBASIC 2.2 Release Notes

New Features

1. •Three new functions in the Math class support fast, accurate numeric integration. Choose from two forms of the trapezoid rule or Romberg integration. If you need Simpson’s rule, keep in mind that Romberg integration of order 2 is equivalent to Simpson’s rule.
   

2. •PlotFunction.setFillColor shades the area under a curve. This is perfect for use with the new integration calls, making it easy to show the area being integrated.
   

3. •LU decomposition is a workhorse algorithm for linear algebra, especially for systems of linear equations. While the techniques are well known, implementing LU decomposition can be tricky. LUDComp and LUBackSub makes it easy to use this powerful technique on your own problems.
   

4. •Math.polyFit implements linear regression. Do linear fits of the form y = A + Bx, or polynomial fits like y = A + Bx + Cx^2. Once you have the fit, use Math.poly to evaluate the polynomial for a given X, or Math.rSquare to find the goodness of fit.
   

5. •Find zeros of a function with the Math.zero function. This returns the X location where the function crosses the X axis. With a simple subtraction, this allows solving an equation for any Y value.
   

6. •Math.mean, Math, stDev and Math.var give easy access to statistics about an array filled with sample values.
   

7. •Math.Gamma, Math.logGamma, Math.err and Math.errc add the basic special functions for probability and statistics.
   

8. •Get uniformly distributed random numbers designed for Monte Carlo simulation using the new Math.rand call, which generates random numbers using the Mersenne Twister algorithm. Math.norm returns normally distributed numbers, and Math.setSeed sets the seed used for random number generation. Of course, if you don’t set the seed, the system clock will be used.
   

9. •Math.isNaN and Math.isInf make it easier to test for numeric results that are not a number (like taking the square root of a negative number) or infinity.
   

10. •Math.PI returns π to full double-precision, so you no longer have to remember that π is about 3.14159265358979323846.
    

11. •A new preference treats the program list the same in iPad landscape view as portrait view, so it slides out of view when not needed. This gives more room for source, debugging and graphics in landscape view.
    

12. •Set the keyboard that will be used when entering text in the console with the System.setKeyboardType and System.setKeyboardAppearance. This allows using, for example, a numeric keypad when numbers are expected.
    

Bug Fixes and Minor Changes

1. •After pausing a program, it took two hits on the run button to unpause it.

Calculator 1.2 Release Notes

Bug Fixes and Minor Changes

1. •Easier navigation of button sets.
   

2. •New button click sound.
   

3. •Fixed intermittent crash on startup.
   

4. •Improved button responsiveness.

Sky Spy 1.1.2 Release Notes

Bug Fixes and Minor Changes

1. •More stable views with iOS 4 and above.
   

2. •New art for retina displays.
   

3. •Preferences save in newer versions of iOS.

Sky Spy 1.2 Release Notes

New Features

1. •Supports the iPhone 5 4 inch retina display.

Calculator 1.3 Release Notes

New Features

1. •Bigger button spacing on the iPhone 5 makes hitting buttons easier.

New Features

1. •Supports the iPhone 5 4 inch retina display.
   

2. •The full screen can be displayed, hiding all techBASIC controls. See System.showGraphics, which now has an optional parameter to show the graphics screen in full-screen mode.
   

3. •There are now getters for control locations. See the X, Y, WIDTH and HEIGHT methods in the Control class.
   

4. •Screen rotations can be detected using a didRotate subroutine.
   

5. •Screen orientations can be allowed or rejected using System.setAllowedOrientations.
   

6. •techBASIC shows a tools button when running on the iPhone, running on the iPad when a 3D plot is displayed, or on either platform when in full screen mode. This tools button can now be hidden. See System.showGraphics, which now has an optional parameter to hide the tools button.
   

7. •Added Math.packXXX and Math.unpackXXX methods to move numeric values to and from arrays of bytes--great for Bluetooth LE programs.
   

8. •There is a new ColorPicker control that lets a user programmatically select a color.
   

9. •Plot.setBackgroundColor now accepts an alpha value, allowing a background to show through a plot.
   

10. •Plot.setAllowedGestures gives a way to block unwanted gestures on a plot.
    

Bug Fixes and Minor Changes

1. •The debugger now shows the class name for variables holding objects.
   

2. •A crash bug in Button.loadImage that occurred when an image was loaded twice has been corrected.
   

3. •Tap locations for setting breakpoints, selecting variables, selecting subroutines, and error locations are off under iOS 6 due to a change in the way Apple calculates line heights. These now work correctly in iOS 5 and 6.
   

4. •Passing NaN as a parameter to Control.setFrame no longer causes techBASIC to crash.
   

5. •The documentation for RESUME has been updated. The old documentation incorrectly stated that control resumed with the line, not the statement, where the error occurred.
   

6. •WebView.setScalesPage is now documented.
   

7. •Calling a function that returned an object more than one time such that the function creates and returns two different objects resulted in a crash; this has been fixed.
   

8. •Assigning one array of objects to another array of objects resulted in a crash; this has been fixed.
   

9. •Omitting the subscript form an array of objects used to access a method caused a crash; this has been corrected.
   

10. •The titles of buttons with transparent backgrounds vanished while the button was tapped; they now show up.
    

11. •Devices for which Apple's BLE implementation could return an NSNumber for the value of a descriptor caused a crash; they now return a single value in an array.
    

12. •The debugger did not correctly display the value of a long integer whose value was outside of the valid range for an integer; it now correctly displays long integer values.
    

13. •DrawText and other font-related commands now work in an Image without the need to explicitly set a font, first. The default font is Helvetica 14.
    

14. •Errors near the end of very long files now show up in the correct location.
    

15. •Fixed a leak in Image.save.
    

16. •Objects returned by System.date did not set the date until it was accessed, always returning the current time. This has been changed so System.DATE returns the time when the original call was made to System.date.
    

17. •Graphics commands like Graphics.stringWidth now work with the predefined fonts, like "Sans-Serif".
    

18. •A memory leak that occurs when using pixel graphics has been fixed.

techBASIC 2.4 Release Notes

Moving Source Files

1. •The ability to move source files to and from techBASIC using iTunes has been removed at Apple's insistence. You can still use iTunes to move data files.

We’ve heard from a number of you in the past asking why we didn’t support downloading programs from various file sharing services. Some would patiently explain to us why it was important, and a few even tried to explain to us how to accomplish the task, assuming that if we had not already implemented the feature, it was because we were to ignorant or unskilled to do so. When we pointed out that the reason was Apple’s policy prohibiting programs from downloading source code, many explained to us the arguments we should use to explain to Apple why this made no sense.

As a result, we expect to hear from many of you about this change. So, in advance, let me just say this: We know. We understand. But Apple makes the rules, and we have to follow them. Apple refused to let us release techBASIC 2.4 until this change was made.

We asked them what harm it had done in the year the feature had been in techBASIC. There was none, but that doesn’t matter.

We pointed out that Numbers (Apple’s spreadsheet) FileMaker Go (A database program from an Apple subsidiary) and even Safari download and execute code, breaking their own rule. That apparently has nothing to do with the decision about techBASIC.

So, unfortunately, we will have to live with this decision. Should Apple ever change their mind, it will take a very simple change to restore this feature. Until then, we will have to resort to using the Share feature to get programs off of iOS devices, and email combined with copy and paste to get programs back onto an iOS device. See the Quick Start guides or reference manual for step-by-step instructions.

Our company policies are simple, reflecting how we like to be treated when we are customers. As with our products, we welcome any recommendations you have for changing our policies.

techBASIC 2.5 Release Notes

New Features

1. •Graphics.setUpdate allows automatic graphics screen updates to be turned on and off, making it easier to create flicker-free transitions while painting on the graphics screen.
   

Bug Fixes and Minor Changes

1. •LOF and LOC support files up to 2147483647 bytes long.
   

2. •POS, TAB and SPC support long arguments and return long values to support strings up to 2147483647 characters long. The documentation has been updated to indicate that strings up to 2147483647 characters long are allowed throughout techBASIC.
   

3. •Arrays can now be up to 2147483647 bytes long.
   

4. •Low battery warnings no longer result in the loss of the text being typed when the warning is displayed.
   

5. •String values with end of line or carriage returns display these characters as _ in the debugger, preventing issues with the display of string constants.
   

6. •LINE INPUT did not always scroll the console so the cursor was visible. It is properly scrolled, now.
   

7. •On the iPhone, use of an external keyboard did not trigger showing the toolbar, making it impossible to do searches, undo, redo, get help or share files. THis has been corrected.
   

8. •Rotating the screen now resizes plots. This will also reposition them, so if manual positioning is used, be sure to redo the manual positioning in the didRotate subroutine.
   

9. •Running a program in full screen mode on the iPhone, then running another program that is not in full screen mode, did not reset the size of the graphics screen. It is resized, now.
   

10. •The documentation for the didRotate subroutine did not point out that it is only valid in full screen mode. The documentation has been corrected.
    

11. •BLEDescriptor.value flagged an out of memory error if the descriptor value is empty. It now returns an empty array of integer values.
    

12. •The snippet shown for the discoverDescriptors method has been corrected.
    

13. •Several samples in the manual had the incorrect syntax
    

   SUB BLEPeripheralInfo (time AS DOUBLE, peripheral AS BLEPeripheral, kind AS INTEGER, err AS INTEGER, msg AS STRING)

They now show the correct syntax:

   SUB BLEPeripheralInfo (time AS DOUBLE, peripheral AS BLEPeripheral, kind AS INTEGER, msg AS STRING, err AS LONG)

• Lots of new samples are provided; these are organized in folders.

1. •You can move, copy or create aliases of programs.
   

2. •There is a new Subs button when editing a program on the iPad. Tap it to get a list of subroutines and functions in the program. Tap the name of a subroutine or function to jump to it.
   

3. •The font size can be changed. See the preferences from the Settings App. Be sure to restart techBASIC after changing the font size so text areas are regenerated.
   

4. •There is now a System.showSource method to show source; it’s handy just before a program ends to switch back to the source view during development.
   

5. •HTTP passwords are supported.
   

Bug Fixes and Minor Changes

1. •Passing an array with empty strings to TableObject.insertRows no longer crashes.

Includes techBASIC App Builder and techBASIC Sampler

New Features

See the Reference Manual or online help system for details.

• The user interface has been reworked to support iOS 7.
• Complete support for BLE slave mode lets you treat an iPhone or iPad as a BLE device. New classes include BLEATTRequest, BLEMutableCharacteristic, BLEMutableService and BLEPeripheralManager. Chapters 9 and 10 of Building iPhone and iPad Electronics Projects show two projects using these commands.
• The following new events to support BLE: BLEMutableCharacteristicInfo, BLEMutableServiceInfo, BLEPeripheralManagerInfo and readyToUpdateSubscribers. The BLE class has a new method to support BLE slave mode: newBLEPeripheralManager. BLEService adds the isPrimary method.
• A new method, Comm.isReadyForOutput, allows an app to check to see if a TCP/IP, HTTP or FTP port is ready to receive output.
• New samples have been added to the O’Reilly Books folder, including BLE Chat A, BLE Chat B, Paddles,  Left Paddle and Right Paddle.
• On the iPhone, dismissing the keyboard now saves the source immediately.

Bug Fixes

• On the iPad, source code no longer overwritten the variable and stack display when the Run button is pressed while the source view is visible, the keyboard is visible when the run button was hit, and a breakpoint is hit.
• Data folders are no longer copied to the source view when techBASIC starts.
• Copying a program while it is being edited now copies the version with editing changes, not the unchanged version on disk.
• Full screen mode on an iPhone no longer shows the button bar at the bottom of the screen.

• The behavior for bitmapped graphics was ill defined on screen size changes. The defined behavior is to repaint the bitmapped image at the top left of the new screen area while maintaining the original image size.
• The date and time formats have been updated to give more information and to respect local time and date preferences.
• Plot.setTitle and other graphics commands now accept Unicode characters.
• Choking the console with too much text may still produce long delays (use System.clearConsole), but will no longer cause iOS to think the app has hung, which resulted in terminating the app.
