Sharp PC-1500A Compiler

[Josef]

Has anyone tried this program? Unfortunately, it doesn't work for me, and after running RUN, some initialization takes place without error, but the program exits and DEF commands don't work.

No, have not used that one. I use the TASM extension I wrote for VS Code:

Also helpful is the PC-1500 library builder:

Thank you for the info. The program as such works, in fact all commands work, only the IF...GO command doesn't work, strange. But GO itself works.

Heureka, I figured it out!

In line 6510, it should not be &B5 but must be &BE (SJP i,j) instruction at address D0D2H, where two variables are compared.

The program actually couldn't work for anyone all the time, there were two errors.

3500:POKE P,&B5,&79,&AE,&38,&D2,&B5,X,&AE,&38,&D3,&B5,&79,&AE,&38,&D0,&B5,Y

6510:POKE P+18,&BE,&3A,&C4,&B5,ZZ,&BE,&D0,&D2,&89,2,&8E,3,&BA,Y,Z

I would stress to users that the _STOP function is absolutely necessary, otherwise the program will "wander" in RAM.

I will improve the program with other functions like SIN, COS, TAN or LOG.
