Sir, But the text Data I have Given as Sample will be changing for each File I process than How will manage it. Can I Use FILETOSTR() in code in place of


Changing a little bit the reg expression I showed before, as the three digits before the total were different that what you showed before (and remember to change the text endtext to filetostr:

text to lcString noshow flags 1 pretext 1 + 2 + 4
&
Endtext
