Cetin:

I have taken your first suggestion and modified it. I am having a problem that I hope you can help with. There are 2 items that I am searching lcfile for: lcjoint, and lcsearchtext. Once Lcjoint is found, I want to continue the search in lcfile from that point to find lcsearchtext, not from the beginning of lcfile. Right now, it finds the occurrence of lcsearchtext from the beginning of the file. Any ideas? Thanks.

lnlines = ALINES(arrlines, FILETOSTR(lcfile))
IF ATCline(lcjoint, FILETOSTR(lcfile))<>0 &&found joint line
ix = ATCline(lcsearchtext, FILETOSTR(lcfile))
IF m.ix + m.rowoffsett =< m.lnlines &&check if offsett is in range

*perform some calculations
