ASM not working on HP 49G+

[John Colvin]

I have been playing with the development functions on my 49G+ and I am unable
to assemble a test file using the ASM command on my 49G+ that assembles without errors on my 50G. I get numerous errors on the 49G+ with the asm error:Invalid file.
Here is the test source file:

LA 45A0
A=DAT0
D0=D0+5
PC=(A)
@

The exact same file assembles on my 50G without any errors. Is there a flag or other setting that I need to set or clear to get the assembler to work?

Are they both the same ROM version (s/b 2.15)?

Does the assembler work at all?

Does it work for SysRPL files OK, and only errors on ML, or does everything produce errors?

Try to disassemble a simple RPL program, they reassemble it; this should verify if all the plumbing is connected.

A couple things come to mind...

1) I believe you are missing a field designator in that second line; it should be "A=DAT0 A" for the Saturn code to compile correctly.

2) Have you installed the extable on your 49g+? I believe this program should still compile without it, as you aren't using any entry point definitions in the code. However, you'll most certainly need it later with other programs.

Hope this helps!

Yes: Flag -92 must be clear (asm mode), not set (SysRPL mode).

Yes, Joe thanks. That was the problem.
