09019: Data Set Has An Invalid DS1LSTAR Value

    FILE:             DAA Data Set Allocation File
    SAS FILE NAME:    DETAIL.VCADAA01
    SOURCE LOCATION:  prefix.MICS.USER.SOURCE(DYVCAEXC)

    SEVERITY:         Warning       (SEVERITY='W')
    MANAGEMENT AREA:  Performance   (MGMTAREA='AVAILABILITY)

    PURPOSE:  Identifies when the data set has an invalid
value for DS1LSTAR (last track and block used in TTR format).

    RATIONALE:  The value for DS1LSTAR is used to set the
value for space used in tracks (DAASPACU) for non-VSAM.
This value sometimes can be corrupted if errors occur during
CLOSE processing.  Data sets with an invalid DS1LSTAR should
be investigated and repaired if possible with the appropriate
utility function (COPY, COMPRESS, EDIT(SAVE), etc.).

    DEFINITION:  This exception is detected when the value
for DAALSTAR (read in from format 1 DSCB field called
DS1LSTAR) exceeds its maximum valid value of x'FFFFFF' or
16777215.

    EXCEPTION STATEMENTS:  The SAS statements identifying the
