Why don't Axe Parser programs have a separate section in the archives?
|

Answer
|
Axe Parser
is a compiler for an alternative programming language on the TI-83 Plus/TI-84
Plus series. Visitors who notice that separate sections in the archives exist
for programming languages like BBC BASIC,
Grammer,
NewProg,
and so forth, often ask why Axe programs are placed in the “asm”
directory rather than having their own section.
The reason is that Axe is a compiled language, which means
Axe programs are converted into raw ASM programs. Therefore, as far as the
calculator is concerned, there is no difference between an Axe program and an
ASM program. Languages that do have their own sections in the archives
cannot run directly on the calculator without an interpreter or other support
program or library. These programs are easy to categorize.
Maintaining a separate Axe section in the archive would be very difficult
since authors are not required to indicate what assembler or compiler they
used when they upload a file. Because the final program variable is
just like any other ASM program, there is no way to tell for certain that
the program was created with Axe, especially if the author does not mention
this fact or include the source code (neither of which are requirements for
uploading files into our archives).
The TI-89, TI-92 Plus, and Voyage 200 sections of the archive
demonstrate another example: Many of these programs were actually written in
the C programming language and then compiled into a 68K ASM program. Yet
we don't have a separate C section for the same reason—from the user's (and
calculator's) point of view, there is no difference, and again, there is
no easy way to accurately determine whether the program had actually been
written in C before it was compiled. But there is a noticeable
difference between TI-BASIC, ASM, and interpreted-language programs (NewProg,
BBC BASIC, etc.); the latter require a separate interpreter program to run,
and the procedure for running the programs is usually different from that of
ordinary BASIC and ASM programs. Thus, programs for these languages have
their own sections in the file archive.
