That’s right.
If it can be both at the beginning of the line or not, you could just define
comment = ;[a-zA-Z0-9]+
Cheers,

Hi,
I'am new to JFlex and started with a simple scanner for assembler text files.
A comment line in this assembler starts with ';' and kann appear at the beginning of a line, or somewhere after an expression.
In the macro section I defined a macro for comments as follows:
comment = ^;([a-zA-Z0-9]+) | (;[a-zA-Z0-9]+)
But running jFlex always stated:
Syntax error.
comment = ^;([a-zA-Z0-9]+) | (;[a-zA-Z0-9]+)
^
where he points to the '^' sign.
Why can I not use the legal '^' sign here for referencing the beginning of a line?
Best regards

Hi,
after reading the manual again, I found the reason in chapter 4.2.11 Macrodefinition:
... must not contain the ^, / or $ operators.
