SIZRECINV, Size of record invalid (ERR=156)

   Explanation: The program contains a COUNT or RECORDSIZE
   specification that is invalid because:

     - COUNT equals zero.
     - COUNT exceeds the maximum size of the record.
     - COUNT conflicts with the actual size of the current record
           during a sequential file UPDATE on disk.
     - COUNT does not equal the record size for fixed format records.
     - You specified a record size in the OPEN statement that was
       unequal to the actual record size established when the file
       was created.


User Action: Supply a valid COUNT value in the PUT or UPDATE statement
or a valid RECORDSIZE in the OPEN statement, whichever is applicable.
