Screen management problems

This information provides the documentation requirements and diagnostic procedures for problems displaying data on the screen.This information deals with five types of screen management problems:

Function error (incorrect screen management for mode).
Exception responses.
Extra or missing data.
Data is not placed correctly on the screen.
Data appears to be translated incorrectly.

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

Note: Problems with incorrect screen sizes are addressed in Screen size problems.

The recommended documentation is:

VTAM® full 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 creates trace entries for 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.
Dump of CSA storage and the user's address space.
This is required only for address space ID TPUT errors.
May require a full PIU trace or CCW trace with data option.
