"embedded" short blocks:
Hi, All,
Is there an "easy" way to find any "short blocks" that might exist in a
FB dataset? We don't have DITTO (IBM File Manager), and I haven't found
a way with File-Aid yet.
TIA,
-jc-
There is no harm in short blocks (which would normally only occur
with multiple file extensions due to DISP=MOD) in a FB Dataset.
Finding one embedded in a FBS Dataset OTOH is BAD NEWS.
The simplest way I know to find them is to write a Q&D Assembler
program to read the file via BSAM and check the BLOCK-SIZE of each
block read. You've found one if a short block is NOT followed by EOF
(ie: If you find another block after reading a short block). There
also may be something useful on the CBT Modes tape.
