Hi,

I have a FD section (for a tape file) that has two 01 level record layouts
of same size X(185).

Do both of the record layouts point to same memory area?
can we refer Data populated into one record layout using the other layout's 01 level.

regards,
sasi patha

Yes, both 01s point to the same point in memory, in the I/O buffer actually (unless you are using awo on output).
Sorta of like two 01s in linkage that you had SET to the same address.

Anything else?

Bill
