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? ;)

A traditional VMS language (Cobol,Fortran,Basic,Pascal) and builtin

Using SEARCH and then a simple Basic program is not that much work.
For example:
SEARCH File1.txt "some text" /output=File2.txt
1 On Error Goto 90
10 Open "file2" For Input as File 1%
Open "File2" For Output as File 2%
20 Linput #1%, Z$
Print #2%, Mid(Z$,?,?)
Goto 20
90 GoTo 99 If ERR=11
On Error GoTo 0
99 End
Simple
No having to know whatever is your favorite utility
I seriously doubt there would be much fewer characters
No, I didn't try it ...
