Get file & line using MASM

[Jerry van Dijk]

[it seems I cannot post to comp.lang.asm.x86, so I am trying here]

Using MASM 6.15, I have an assert macro for GUI programs that pops up a
messagebox with some data. I would like to at the filename and linenumber
to it (like __FILE__ & __LINE__) in C. I found @FileName and @Line of course,
but it seems they are only useful with .ERR, since I cannot find a way to
get their actual content during assembly to be stored in the data segment.

Anyone an idea how to archive this ?

Thanks,
Jerry.

something like:

% db "VeRsIoN= &@FileName &@Date &@Time",0

works for me.

it doesn't for me, it complains about either a syntax error for the '&'
when used with a local label, like

Oops MACRO
LOCAL Skip, Name
jmp Skip
Name BYTE &@FileName, 0
Skip:
ENDM

or about the content of FileName being an undefined symbol when used with
an anomymous label, like:

Oops MACRO
LOCAL Skip
jmp Skip
% BYTE &@FileName, 0
Skip:
ENDM

Seems to work for me :-) How about some Quotes? :-)

BTW, the % is required to force evuatation of the expression.

Sample:

Oops1 MACRO
LOCAL Skip, Name
jmp @f
Name label BYTE
% db "&@FileName", 0
@@:
ENDM

Oops2 MACRO
jmp @f
% BYTE "&@FileName", 0

Ouch, of course, that's it... My only excuse is that I never had to use any
predefined symbols before. Thanks for your help.
