The answers so far in this thread have all honed in on "escape key" meaning "how do I write a regex that matches this as a delimiter". One other meaning for "escape" that I would suggest is likely as valid is "how do I write the data so that it can also include a pipe character?" For that, we can't answer as quickly. We'll have to write both the parser and specify the data for that parser. Anyway, I just saw it amusing that everyone went for one end of the problem when it might be the other. -- Randal L.

Well, the really depends upon what you want to do and why. If you're just splitting the data: `my @data = split /\\|/, $string;` [download] Cheers, Ovid Join the Perlmonks Setiathome Group or just click on the the link and check out our stats.	[reply] [d/l]

Try `split(/\\|/, $line)`.	[reply] [d/l]

well here's a possible solution for the output side... note the lack of an "escape", works with one too. `#!/usr/bin/perl use strict; my $a="foo"; my $b="bar"; print join("\|",$a,$b);` [download] produces.. `foo\|bar` [download]	[reply] [d/l] [select]

Are you reading the data from another source or are you generating the data?	[reply]
