Hello. I use a ?! macro to stringify all catched line for string processing and other stuff. In fact, I have designed a small domain specific lang. " and ' have not the same meaning (in my lang). But when I stringify line containing " it's converted into '. I can't dissociate what the user wanted. For instance:

Code:

calminstruction _? _params?            
    _init const __params, _params                                              
    stringify _params                                                          
    _asmcmd =display "[", __params, "]"          
end calminstruction                                                            
                                                                               
_ "abc" ; display ['abc']

There is no way I can display ["abc"]??
Thanks.

This is a bit of information that is lost during fasm's tokenization, there is no way to get it back. The string token would probably need to be extended with additional byte to fit such information into.

Ok. I've re-read the man (lexical part) and I didn't known that double and single quote were apart from the +-/*=<>()[]{} group. So technically you can define variable with quote inside it, like:

Code:

a"b? = 3

Pretty funny.

It can be really helpful with numbers too:

Code:

bitfields:
.mask   = 00'111'000b
.one    = 00'001'000b
.two    = 00'010'000b
.three  = 00'011'000b

Yes. I forget that too. Underscore also work but single quote is far better. You can mix both also.
