https://communities.sas.com/t5/SAS-Programming/Regular-expressions-perl-sas/m-p/491635#M128981 <P>I am looking at someone elses code and have a question. Below is the code. Where it says: ^DR DUE does that mean the string starts with DR DUE? I am new to perl regular expressions. Also, where ATM\/(DEP|WTD) does this mean match ATM/(DEP|WTD) in the string? However, I thought that ( and ) were metacharacters too. Thanks for your help!</P><P>&nbsp;</P><PRE><CODE class=" language-sas">Removed<BR /></CODE></PRE> Fri, 26 Apr 2019 15:50:15 GMT user112a2 2019-04-26T15:50:15Z https://communities.sas.com/t5/SAS-Programming/Regular-expressions-perl-sas/m-p/491635#M128981 <P>I am looking at someone elses code and have a question.
