NULSUBSC, XXXX Null subscripts are not allowed for current region: FFFF
Run Time/MUPIP/DSE Error: This indicates that a global variable specified a null (empty string) subscript in a database file FFFF which does not accept null subscripts. The leading context (XXXX) specifies more about the event or location of the issue. This message should be followed by a message presenting the reference containing the null subscript.
Action: Look for the source of the null subscript(s) and consider whether they are appropriate or due to a coding error. If they are appropriate, use MUPIP SET -NULL_SUBSCRIPTS, and remember to make the same adjustment with GDE CHANGE REGION -NULL_SUBSCRIPTS to ensure the next time you recreate a database that the characteristic persists.
