I have an input file that has email addresses in them with mixed cases. I want to remove email addresses that are from a particular domain. The email addresses come in mostly lower case, but there are few that contained mixed case or all upper. Is there a way to make the comparison not case sensitive?

I checked the manual for a way to convert the compared text to upper (or lower). I didn't see a TRAN=LTOU on an OMIT COND statement. I was considering putting the LTOU conversion in another step where I would convert the whole file to uppercase, but I was looking for an all-in-one.

This OMIT worked for most, but I'd have to code for the different variations that a user could possible type (i.e. @SomeDomain.com, @SOMEdomain.com, etc).



I guess this is what I was trying to achieve. =)

You can use a DFSORT job like the following to do what you asked for. I assumed your input file has RECFM=FB and LRECL=100, but the job can be changed appropriately for other attributes:
