SYSGEN AND SYSGEN-RELATED PROCEDURES
Step Action
9. For an online sysgen, Enter H (host) and
press <ENTER>.
Request the host operator to vary the
printing system online.
Notes:
You must use a host utility program to
advance the SST to the next-to-last file.
This file, which consists of 128-byte and
8192-byte fixed-format blocks, must be
deblocked to 128-block records (without
adding page numbering or reformatting the
data) before transmission to the LPS. Refer
to the appendix for an example of a typical
host utility program for file transmission.
If you have a user-created SST for an
online system, you do not need to advance
the tape to transfer the first file (which
contains the new sysgen processor).
Simply mount the tape and initiate the file
transfer process at the host.
Enter N and <ENTER>.
10. Request the host operator to vary the
printing system offline, then enter C. (You
need not press <ENTER>.)
