Screen size problems

This information provides documentation requirements and diagnostic procedures for screen size problems. Two major types of errors occur:

Choose the one that most closely matches your symptoms and follow the procedure for that problem.

Recommended documentation includes the following list.

Note: All of the traces may not be required. Read the diagnostic procedure before you get them.

VTAM® buffer contents trace.
To see the data in the buffer contents trace, set CONFTXT=NO in the TSOKEY00 member of SYS1.PARMLIB before starting TSO/VTAM.
GTF trace of SVC 93 and SVC 94 entries. See Table 1 to determine what document describes the SVC 93 and SVC 94 entries.
TGET/TPUT trace.
The TGET/TPUT trace records all TGET/TPUT/TPG data except address space ID TPUTs.

You can get the TGET/TPUT trace by issuing the MODIFY TRACE command with TYPE=TSO. The MODIFY command is described in z/OS Communications Server: SNA Operation.
May require a full PIU trace or CCW trace with data option.
