DSNT579I The first character of the DB2 subsystem command prefix entered is incorrect

Explanation
An incorrect DB2 COMMAND PREFIX FIRST
CHARACTER is entered.

The DB2 COMMAND PREFIX FIRST CHARACTER
field must contain a character,  except for the
ampersand (&), from the table in COMMAND PREFIX field. To
use & for provisioned Db2 subsystems, accept the default value in this
field, and then edit the dsntivin variable input file directly in zFS.

This message is issued by the following panel: DSNTIPAP.

System action
The panel is re-displayed and the cursor is placed on the field in error.

User response
In the DB2 COMMAND PREFIX FIRST
CHARACTER field, enter a valid value.
