ti99basic - TI-99/4A BASIC as a scripting language

This is a version of Texas Instruments' BASIC as found in ROM on the TI-99/4A.
Note that this is not TI Extended BASIC. It is also not the same as the
TI-BASIC used in TI's line of calculators. You can use it in interactive mode
or pass a BASIC file as a command line parameter.

This source does not emulate TMS9900 code. The function of the original TMS9900
code is handled by native code. The Graphics Programming Language (GPL) code is
still run in a virtual machine just as it was on the original hardware.

 Download

 * 2009-08-12 Version 1.0 (Win32 binary, OS X binary, source)

Windows users should also install Microsoft Visual C++ 2008 SP1 Redistributable
Package.

 Compatibility

It has been tested with

 * Mac OS X 10.4/10.5/10.6 i386/x86_64/ppc (GCC 3.3/4.2)
 * Ubuntu Linux 9.04 (GCC 4.3)
 * Windows XP (Visual Studio 2008)

Other CPUs, operating systems and compilers should work, too.

 Compiling

To build from source you will need a copy of Perl and the original TI-99/4A
ROMs. These files should have the following MD5 sums:
6cc4bc2b6b3b0c33698e6a03759a4cab *rom.bin
ed8ff714542ba850bdec686840a79217 *grom.bin

Other versions of the files are unlikely to work.

 Usage

The specifics of the dialect of BASIC used by the TI-99/4A are available in the
original User's Reference Guide. The Cassette, Disk, and Sound devices are not
currently emulated. You can use tibasic in interactive mode by just running the
binary without parameters, or you can specify an ASCII-encoded BASIC program on
the command line. You can also use tibasic as a UNIX scripting language by
adding a hashbang line to your BASIC program and making it executable.


$ ls -l hello.bas
-rwxr-xr-x 1 user user 43 2009-08-06 23:55 hello.bas
$ cat hello.bas
#!/usr/bin/tibasic
10 PRINT "HELLO WORLD!"
$ ./hello.bas
HELLO WORLD!

Also included are 3 sample programs in the 'samples' directory. The first two
are sample games provided in the original manual; these expect upper-case input
at the prompts so it may be convenient to turn on Caps Lock when running them.

Filename Description
codebreaker.bas A clone of Mastermind
secretnumber.bas Guess the secret number but with an unusual twist
sieve.bas Prints out prime numbers from 1 to 120,000
