regex testing for multiple values

grashoper has asked for the wisdom of the Perl Monks concerning the following question:

I am trying to test for different account codes using a regex and can't quite get it to work as desired, keep getting a syntax error, I am not sure what is wrong so was hoping one of the esteemed monks here would give me a clue. I really need for this check to encompass multiple values and am only looking to match these 3 letter account codes and do something if there is a match.

 if ($Session->{'usrSystem'} =~"?:SND|ARM|PRO|NOR|IND\"*/s)

I think what all these responses are trying to say is that you want something like: `if ($session->{'usrSystem'} =~ m/(?:(?:SND\|ARM\|PRO\|NOR\|IND\|) )/s` The (?: ) just tell the parser to not capture the matched strings (i.e., not to produce the $1.. variables). I presumed from your version of the Regex that you wanted to match 0 or more occurances of the 3 letter account codes (which was why you put the in it). I also presume you meant to have a white-space character (or more specifically a blank) since you put a space between the \ and the "...is that right? I also presume that you put the /s at the end to treat the string a single line and that . will match embedded newline characters. Is that correct? ack Albuquerque, NM	[reply] [d/l]

I don't really want the space but your other assumptions are correct,I will try your suggested statement, and post back if I have any further problems. Thank you for the help.	[reply]

Regexes should be delimited by `/ ... /` or start with an <m>, like this: `m{SND\|ARM\|PRO\|NOR\|IND}` or `m/.../`. single quotes delimit strings, not regexes. Update: fixed markup, Fletch++	[reply] [d/l] [select]
