The <c> block looks like an artifact from his HTML, if that's what you mean--it shouldn't show up in your code... That is, he was saying if you aren't going to use forward slashes to delimit your regex, then you need to prefix it with m: `if ($blah =~ m#regex here#options here)` instead of the usual `$blah =~ /regex here/options here` or what have you. (In your post, the regex doesn't appear to start with a forward slash.) I'm a peripheral visionary... I can see into the future, but just way off to the side.	[reply] [d/l] [select]

...all I get is a syntax error mismatched right bracket That's not what I get when I run your snippet (commenting out the `do something` lines). I get: `syntax error at [...] line 12, near "{"` where lines 12-13 are: `elsif {` [download] Did you perchance mean `else` rather than `elsif`?	[reply] [d/l] [select]

if ($Session->{'usrSystem'}=~/{IND\|NOR\|PRO\|ARM\|SND/s) I don't understand why its not executing the code block, all I get is a syntax error mismatched right bracket for now I wrote as a series of if statements its ugly but it works. See bolded areas.	[reply]

Update: Oh, did you want there to be a literal curly brace before IND but not the rest? If so, ignore the rest of this post. Yeah, you have a mismatched bracket there :) Try: `if ($Session->{'usrSystem'} =~ /IND\|NOR\|PRO\|ARM\|SND/s)` Note that you'll want to surround the alternations in parentheses (these kind) if you want something like: `/^(IND\|NOR\|PRO\|ARM\|SND)/` I'm a peripheral visionary...

Right idea, wrong bolding. It's misleading on the OP's part,but that quoted statement is not a syntax error. The trailing slash closes the regex and the right paren properly terminates the if clause. The right paren is not matching the left brace - that left brace is part of the regex and is treated as a literal.	[reply]

"Mismatched" is so hard to understand? Did you try taking it out? `{...}` surrounds quantifiers in regexen, like: `=~/[A-Z](1,3}/ # Match any char in the range A-Z no fewer than once, # nor more than 3 times` [download]	[reply] [d/l] [select]

Did you try it out? Did you? :) `$_ = '{IND'; print "Ok\n" if /{IND/; ____ Ok` [download] Update: It seems that I misquoted ww, who actually wrote 'Did you try taking it out?'. My point remains valid, though. The problem is not with the regex, it is somewhere else in the code.	[reply] [d/l]
