Here's a simple RegExp function that I wrote a while ago for my own
use with QBASIC. It covers the most useful bits without being a full
fledged perl compatible one. The usual caveats apply about Usenet
splitting long lines unexpectedly and about my not being responsible
if you come to harm as a result of using it for purposes which I never

Regex and BASIC?

ca...@libertybasic.com (libbasic) — Mon, 15 Sep 2008 20:57:13 UT

I'm curious how BASIC programmers would design Regex features for

Actually there can be good reasons for worrying about it. If the
program is running on a (battery powered) laptop, the likelihood is
that the battery will run down much more quickly even if you don't
notice that the computer is slowing down. Even with a mains-powered
PC, all that extra unnecessary power consumption is not very
