Hello.

Could somebody tell, how to convert macro argument into string.
Suppose I have a macro ToStr which accepts two arguments - one is symchain, another is result. When I call this macro with symchain equal to A+B, I need to receive string constant 'A+B' in result (so I could display it for example, or use with db directive). I tried ` sign, but i converts to string only A symbol.

Thank you.

Siberian,

Backtick converts only one following token to string. You need to irps over symbols in symchain. There are several restrictions on tokens in the list to iterate through, though. Lone backslash, single/double quotes and semicolon simply don't live long enough to get preprocessed. Macro operators and braces can be backslashed as usual, but this depends on dynamic macro nesting level.

Already found the way myself.

Thank you baldr. I knew about irps, but just didn't realize that concatenating two string constants with # sign will produce new string constant. I tried several things, but couldn't find a solution, so I posted a message and went to a shower. While being there, I got an idea to try this concatenation, and it worked. The same time, you posted a reply, so you just reassured me that this is the right way. One thing bothers me though. This reequ structure is it really necessary?

Siberian,

reequ is an utility macro: it replaces current value of symbolic constant.

So then we also need utility macros for struc and for macro directives?

Siberian,

I've used struc-macro because that way reequ will look like equ directive. There are differences though, due to macro operators.

struc and macro are reserved words, they can't be used as a macro name.
