Hi Ralph, If I understood well, do you have plans to make an alternative "tools" directory in your next release? In that case I would be glad to propose my "terminal" for your collection.

I've got the similar effect with my Cygwin+'rx'. One of the problems was the COM port speed: it was 9600 instead of 2400. Have you checked your port settings? Anyway, something other remain... I will try it again tonight. Sergey. (...) (25 years ago, 15-Dec-99, to lugnet.robotics.rcx.pbforth)

Your statement of the LONGEST match may be correct for TCL but not for perl! look at the second regexp: the '?' inside means expand to the smallest match ( this is a perl specialty i think) the only thing is, if you nest comments like ( (...)

Hello, i've written a little perl script, which removes white spaces and comments from a forth source code. If called without any parameters, it reads from STDIN and writes to STDOUT.
