Question Help on extracting portion of string
Hi Gurus,

I've some sample of my log information as shown below.

Code:
-> Processing ABCD123456 
This is tp version 372.04.57 (release 700, unicode enabled)
This is R3trans version 6.14 (release 700 - 05.03.09 - 08:28:00).
unicode enabled version
R3trans finished (0000).
Warning: Parameter DBLIBPATH is no longer used.
tp finished with return code: 0
meaning:
  Everything OK

-> Processing GFSG988221
This is tp version 372.04.57 (release 700, unicode enabled)
This is R3trans version 6.14 (release 700 - 05.03.09 - 08:28:00).
unicode enabled version
R3trans finished (0000).
This is R3trans version 6.14 (release 700 - 05.03.09 - 08:28:00).
unicode enabled version

tp finished with return code: 4

How to extract only a portion of the log information with the following desired output?

Output:
--------
-> Processing GFSG988221
A tool used by tp produced warnings

Appreciate if you could advice and help.

Thank you.



Regards,
Peter.
