Text processing on VMS

I've got a text file with data that I want to select lines matching
certain character strings, then extract string values from the selected
lines by character position. On Unix, I would use awk or Perl. Does VMS
have a similar tool, should I use my favorite programming language and
call the STR$ RTL, can I write a TPU script to do this, or should I
transfer the file to a Unix box and user awk or Perl? ;)
