SASFILE awork.abc.data OPEN;

Several datasteps...

.........

Can anybody tell the effecient use of above statement...

I think you will only find it useful if you have to run multiple procs on the same file and have enough memory available.

The first use takes slightly longer than not using it, but subsequent access of the same file should reduce processing time.
