Need to find a multiple line block and replace with a multiple line block

I would perfer to use cut and paste to do this but I can't find a GUI to do this with. What I want to do is to find a multiple line block of code like

Exit Sub

Log_Handler:


then replace it with

GoTo RSLogRtn
Exit Sub

Log_Handler:


Basically it is just an insert, but I may want to replace whole line blocks of code at some time. How can this be accomplished. I tried using V-Grep but to no avail. It will only replace the line block with a string and you can't use expressions in the replace test.

can you elaborate more by giving your exact inputfile and desired output.

Try this then...

Code:
>cat file
Exit Sub
 
Log_Handler:
 
>awk '/Exit/{err=$0;getline;getline;if($0 ~ /Log_Handler:/){print "GoTo RSLogRtn" RS err RS RS $0}}' file
GoTo RSLogRtn
Exit Sub
 
Log_Handler:

I will try it. Does this find/replace every reference in the file?

Old 08-22-2009
yes, if it is the same as your example. And if that's how you wanted it, redirect to another file.

Yes, to redirect the whole contents with the changes to another file.

Thanks.
