HP 9000 series 200/300 BASIC Compiler, Assembler

[Paul Berger (Canada)]

The utility for linking to compiled Pascal and assembler is called CSUBs and you need the correct version for the version of BASIC you are using. The newest one that I know of that is readily available is version 4.0. I have used it to build a CSUB from a compiled Pascal (3.1) routine. The CSUBs package consists of libraries that appear to provide the linkage for calling from BASIC. At this time it is unclear if there are substantial changes between versions or if it is just a flag in the code somewhere, but I do know a CSUB linked with the version 4 libraries will not run on version 5.1.

The assembler for these systems is part of the Pascal package, which take some getting used to as it is the whole USCD-P environment, however fortunately it generates native 68K code rather than P-code. Other useful tools in Pascal are a debugger and un-assembler.
