I'm suffering from severe brain fade and can't remember how to code a 
lookahead. I've searched high and low for an example to follow and even read 
the RPG manuals!!! ;)

Before processing the record just read, the program needs to know if the next 
record belongs to the same group.

Can anyone whip up a bit of sample code?

Thanks
