In (8-bit) MS BASIC, you can do this:
10 PRINT10:REM this is a remark
Or even:
20 PRINT20:' this is a remark too
But I came across some code, obvious in retrospect, that does this:
30 PRINT30' this is also a remark
In my flex I have these rules:
REM.* { yylval.s = strndup(yytext + 3, y
First of all, my commiserations.
Second, you need to deal with this in the scanner, not in the parser.
Essentially, any scanner that processes random data (aka comment) as if
it were program statements is going to fail miserably. And so will any
parser that attempts to make sense of the maels
