Sudha,
Nah. It only reads a block of records. The difference is the key
comparison for ending the group is done in the program ( SomeKey <>
KeyField ) after the read rather than as part of the ReadE ( SomeKey )
opcode. This logic requires work variables for all the key fields to be
compared against.
