Is there a way to expand macros with Borland's TASM ? I'd like to transform a TASM compatible .ASM file to see all his macros expanded. Couldn't find any options to do that.
Use TASM's command-line option /la to produce an expanded listing. From this listing, you can see the high-level and low-level expansions. This feature works on all versions of TASM down to the initial release in 1988.
For example, let's say you have the following TASM macro:
OUTPUTMESSAGE MACRO hConsole,stringval
LOCAL msg
.data
msg db '&stringval',0
.code
call outputString ,hConsole,OFFSET msg
ENDM ;OUTPUTMESSAGE
And you want to see how the following source is expanded:
OUTPUTMESSAGE hConsole,<This app was assembled with TASM version >
OUTPUTMESSAGE hConsole,%??version
The listing file produced with /la (I happened to be using version 5.4) produces the following:
516 OUTPUTMESSAGE hConsole,<This app was assembled with TASM version >
1 517 0000018F .data
1 518 00000000 54 68 69 73 20 61 70+ ??0000 db 'This app was assembled with TASM version ',0

The columns correspond to [depth] [line#] [offset] [machine_code] [source]. Unfortunately as you'll find, the [line#] column isn't particularly useful. Below is a snip from the TASM5 User Guide that describes the columns:
[depth] - indicates the level of nesting of Include files and macros within your
listing file.
[line#] - is the number of the line in the listing file (not including header
and title lines). Line numbers are particularly useful when the
cross-reference feature of Turbo Assembler, which refers to lines by
line number, is used. Be aware that the line numbers in [line#] are
not the source module line numbers. For example, if a macro is
expanded or a file is included, the line-number field will continue to
advance, even though the current line in the source module stays the
same. To translate a line number (for example, one that the
cross-referencer produced) back to the source file, you must look up
the line number in the listing file, and then find that same line (by
eye, not by number) in the source file.
[offset] - is the offset in the current segment of the start of the machine code
generated by the associated assembler source line.
[machine_code] - is the actual sequence of hexadecimal byte and word values that
is assembled from the associated assembler source line.
[source] - is simply the original assembler line, comments and all. Some
assembler lines, such as those that contain only comments, don't
generate any machine code; these lines have no [offset] or [machine_
code] fields, but do have a line number.
