I have had a further chance to play around with your assembler. First
off, I'd like to say that it looks like it will be a fine one. I am having
a problem with one thing that is most likely something I am doing wrong due
to misunderstanding something or other. The following fragments will serve
to show the problem….
XTRN macro
XREF _LVO\1
endm
call macro
jsr _LVO\1(A6)
endm
…..
XTRN OpenLibrary
…..
call OpenLibrary
This code produces (at "call OpenLibrary") the expected line….
jsr _LVO OpenLibrary(A6)
but I get an error code 48: Unavailable addressing mode used. I tried a
JSR to a label defined within the program with the same addressing mode,
and didn't complain, so I imagine it has something to do with the fact that
the offset I want is externally referenced.
