MAXRL Maximum. Record Length
MAXRL Length of the longest record in the file / library element / Job variable.
This User Option will cause all records of the file/library element to be read sequentially from the first record to the last, in order to determine the length of the longest record. Files with Recform=F, or Rectype=PAM, as well as tape files are excluded, since the record length can be determined from the catalog entry.
