FORTRAN-77/RT MAGTAPE Sequence Number Support for OPEN command 13-Aug-85 * * * P R E L I M I N A R Y * * * NOTE: This kit is for Release 1 of FORTRAN-77/RT only. Support for Release 2 will be provided at a later time. The module OPEN.OBJ is a modified version of the F77OTS routine for opening a file that contains support for MAGTAPE sequence numbers. Link directly with it, or if you are daring, install it in your SYSLIB. A variable $SEQNM, which shows up in the link map, contains the default value to be used for the SEQNUM argument when a .LOOKUP .or .ENTER is performed. A subroutine has also been added to allow $SEQNM to be set from a FORTRAN program. The suboutine is used as follows: CALL MTSEQN ( N ) to set $SEQNM to N. Alternatively, you could SIPP patch the location $SEQNM to contain the value you desire.
