Can anyone assist ? I have a large .txt (115,000 lines) that contains many variable length sub-sections stacked on top of each other; I need to extract each subsection text between Common seperators & save extraction to a seperate text file (with *.LOG extension). The extract file name is embedded in Line 3 of each subsection eg "gOILp_u" Given file size Need to automate/loop/ this RegEx process with a Perl script/function.

For each subsection: ------ Start String: "WinSolve log file created " End String: "Exit" File Name to Save Extracted subsection text to: Occurs on Line 3 of each subsection

(eg1 1st subsection Line 3 reads: 

@ gRSH1p_u @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

[download]

(eg2 2nd subsection Line 3 reads: 

@ gOILp_u @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

[download]

So 1st subsection => saved to c:\data\ws3\sim\LOGS\gRSH1p_u.LOG So 2nd subsection => saved to c:\data\ws3\sim\LOGS\gRSH1p_u.LOG

SECTION (TOP) OF LARGE FILE TO BE SPLIT:------------------ 
WinSolve log file created
@
@ gRSH1p_u @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@
[TRUNCATED SUBSECTION TEXT]
@
Exit
@
WinSolve log file created
@
@ gOILp_u @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@
[TRUNCATED SUBSECTION TEXT]
@
Exit
@
WinSolve log file created
@
@ gTRX1p_u @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@
[TRUNCATED SUBSECTION TEXT]
@
Exit

[download]
etc etc

SUMMARY OF REQUIREMENT --------------

1st subsection, extract all text between "WinSolve log file created " & "Exit" ; save to c:\data\ws3\sim\LOGS\gRSH1p_u.LOG

2nd subsection, extract all text between "WinSolve log file created " & "Exit" ; save to c:\data\ws3\sim\LOGS\gOILp_u.LOG

3rd subsection, extract all text between "WinSolve log file created " & "Exit" ; save to c:\data\ws3\sim\LOGS\gTRX1p_u.LOG etc etc
