Has anyone else come across the following possible bug in lex? I'd
like to ignore certain characters, including vertical tab (\v,
^K, \013, etc.) When I included the line
[ \v\f\r\t] ;
in the source file, vertical tabs fell through. However,
[ ^K\f\r\t] ;
[ \013\f\r\t] ;
works. I'm not thrilled about this, though, because it means
hard-coding a control character or ASCII code.
I'm running Sun's version of lex on a Sparc-2, in case it makes a
difference, but another site has reported the same problem. I don't
know what equipment they have there.
Thanks for any help!

another one. Flex handles it correctly. -John]
