  For the most part, AmigaBasic 1.2 is mostly bug fixes.  The only new
thing I know of is that the new version parses command line arguments.
This means that it is now possible to boot directly from the startup
sequence into a basic program.  The correct paths relative to the
current directory (initially df0:) must of course be specified.

Example:

If AmigaBasic is on the boot disk in a directory called "Basic" and
the basic program is on the boot disk in a directory called "Programs"

   Basic/AmigaBasic Programs/MyBasicProgram

should load AmigaBasic which should then load and run MyBasicProgram.


   One thing to remember however.  When you start AmigaBasic (or any
executable program) from Workbench, the resulting process is CD'd
where you double-clicked.  CLI processes however are CD'd to the same
place as the CLI they were started from.  So if your AmigaBasic program
needs to read in any files (such as bmaps, graphics, etc) or writes
files with no path expecting them to go to certain directory, you
will probably need to add a CHDIR statement to your Basic program
to make sure IT is CD'd where you want.

CHAIN can call in and run another program while preserving all variables.
Or you might want to write out a RAM: or disk file which the other program
could read.  If you want to implement BSAVE/BLOAD type of stuff, see my
AmigaBasic ILBM programs on Extras 1.2 for an example of the kind of
BSAVE/BLOAD that can be implemented with AmigaDOS system calls.
(Better than BSAVE/BLOAD because you can save many different areas of
memory in one file, and can load portions of one file back into various
memory addresses.)
