 NAME       : FCHTAB
 DESCRIPTION: Fetch Table
 DSECT      : FCHTAB
 FUNCTION   : FCHTAB contains an 8-byte fetch/load parameter
              list that points to a 38-byte directory list.
              The fetch table is used when a VSE program
              issues a FETCH or LOAD request without the
              LIST= parameter. NUCON contains the pointer to
              the SYSCOM block (ASYSCOM). The IJBFTTAB field
              in the SYSCOM block points to the fetch table.
              FCHTAB is called by the FCHTAB macro.
