IBM System/360 20 User Manual

When maintenance of the Model 20 Tape Pro-
gramming System is to be performed, the
revised elements are supplied on a tape
reel (or in cards). The retrieval of the
elements from such a distribution tape is
performed in the same way as for initial
retrieval.
The distribution tape may contain the
following items:
1. Distribution-Package Retrie-
va I prog ram.
2.
3.
4.
Any modified program phases
or programs for sequence num-
bers 2 to 13 of the initial
distribution tape.
The modified Tape-Resident
Control programs
Any modified program phases
or programs for sequence
numbers 16 to 30 of the
initial distribution tape.
If item 4 is present:
5. 1* control statement
6. II END control statement
7. Separate set of // CATAL
statements, concluded by the
/1 END statement.
8. Any modified InputlOutput
andlor Easic Monitor macro
definitions, with inters-
persed // PRIOR and II CATAL
statements, concluded by a II
END control statement.
If item 8 is present:
9. Separate set of II PRIOR
and 1/ CATAL statements, con-
cluded by a // END control
statement.
10. Any modified InputlOutput
macro definitions for the
Binary Synchronous Communica-
tions Adapter, with inters-
persed /1 PRIOR and II CATAL

If the CMAINT program cannot be used on the
available machine configuration, the master
deck used for initial system generation
must be updated by replacing the corres-
ponding programs andlor phases. The new
system can be huilt as described in the

All control statements for the CMAIN! pro-
gram except the II fONTB and II ENt control
statements for the TPS Basic Monitor pro-
gram are made available under items 5, 6,
and 7 of the distribution tape. These
items are to be used under the following
