First I would like to say Thanks for the help that I have received so far. I have 2 question on how to use Regular Expressions. Here is an example of the data that I am dealing with. Header Line One ***-*** 0 0 ***-MBO 0 0 2TO-T/V 0 0 2TO-T/O 0 0 POC-CNU 1285 0 POC-A/M 0 15567 Header Line Two ***-*** 0 0 ***-MBO 0 0 2TO-T/V 0 0 2TO-T/O 0 0 POC-CNU 1285 0 POC-A/M 0 15567 1) I am looking for a way to read a line in and look for the first 7 characters. The Characters can start with a a-z0-9 or */ and the fourth character will always be a -. It does this until it reads the line that says "Header line two" which starts the next file. 2) Also how would I do an error check for duplication. What I mean is if for some reason "Header Line two" is skipped over. And the next line is the same as in "Header line one" than I would need to produce an error. how would I go about doing this.
