- Do you have MAXDATA=4096 in your NCP definition on the PCCU statement?
- Does your UNITSZ = your IOBUF size in your VTAM definition? Is your
- MAXBFRU * UNITSZ - BFRPAD greater than or equal to 1296?
-
- I have found that when I use UNITSZ=384 with MAXBFRU=12 and BFRPAD=0 on
- the HOST statement in my NCP definition and set IOBUF=384 in VTAM, I have
- less problems.
