NAME       : IO
 DESCRIPTION: Major CSECT for All I/O Operation Lists
 DSECT      : OPSECT
 FUNCTION   : OPSECT describes the fields that several
              programs use as parameter lists for reading and
              writing on disks and other devices. The OPSECT
              CSECT is pointed to by the AOPSECT field in
              NUCON. OPSECT is called by the IO macro.
