How to read an isam file sequentially. i have assigned all key fields values "" ie empty and trying to read the file in a update logic of a report .

i am able to display UMsg IN BEFORE READ , but not able to display in after read no err and after read err.

control is going to exit logic directly after before read in the group. "

what can be the problem

I was doing sel-only for empty fields, this caused the problem.

removed sel-only from default logic and pro file is read sequentially
