IEC051I

Explanation
A null record segment was created for a PDSE member
containing VBS records processed by QSAM or BSAM; however, the null
segment will not be saved. This attention message is issued only on
the first occurrence.
In the message text: mod
The name of the module which detected the error.
ddname[-#]
DDname (followed by a concatenation number if it is part of a
concatenation and not the first DD statement in the concatenation).

System action
The null record is ignored. On the first occurrence,
an indicator is set in record type 15 in the SMF data set. Processing
continues.

Programmer response
Analyze the program to see if the null record
segments are necessary to operation.
