Hi Tomasz

Can u pls consider the below reg. 'last resort interceptor' (??)...
Quote:
doc says :
(...)
An identifier consisting of two question marks can be used to define a special instruction that is called only as last resort, on lines that contain no recognizable instruction. This allows to intercept lines that would otherwise be rejected with "illegal instruction" message due to unknown syntax.
(...)



can u pls clarify why can do :
Code:
mvmacro ??, <some macro>
    

while the below seem to fail - Fasmg complaining with 'Error: invalid identifier.' :
Code:
mvmacro <some macro>, ??
    


Is this intended / on purpose ?

It's an oversight. The "??" identifier is recognized only when used as a definition target - this was done to make a line like "?? +" be intercepted with complete "?? +" text as argument instead of calling "??" macro with "+" argument. But perhaps there's a better solution - I'm going to look into it.
