DFS1055I label DEVICE COLUMNS TOO SMALL FOR PDB REQUIREMENTS
Explanation
The number of horizontal lines (columns) for the device is insufficient for the screen width requirements of the Partition Descriptor Block (PDB). The label is the name of the DEV statement requiring the PDB.
System action
A return code of 12 is set, and processing continues with the next DEV, MSG, or FMT definition.
Programmer response
The 3270 symbolic name (3270-An) used in the TYPE keyword of the DEV statement might specify an incorrect screen size. Alternatively, the PDB used in the PDB keyword of the DEV statement might be in error. Correct the error, and rerun the job.
