IBM System/360 20 User Manual

The Core-Image Service program (CSERV)
enables the user to check some or all of
the ~rograms or program phases contained in
the core-image library of his system tape.
It also enables him to extract (i.e., Funch
out) some or all of the contents of the
library for such purposes as making correc-
tions or creating back-up.
The program is used to print, in hexade-
cimal notation, one, several or all program
phases from the library, and/or to punch
the ~hases into TXT and END cards. It can
also be used to print and/or punch the
Tape-Resident Basic Monitor program, which
is not contained in the program library.
Output from the CSERV program may be
used as input to the Core-Image Maintenance
program or to the Load System Tape program.
The CSERV program must be contained in
the core-image library of the user's tape-
resident system if it is to be used.
I/O DEVICE ASSIGNMENTS
The following symbolic de~ice addresses are
used in preparing and performing the execu-
tion of the CSERV program:
SYSRES -- Re~uired. Assigned at IPL time.
Refers to the tape drive on which
the system tape is mounted.
SYSRDR -- Re~uired. Refers to the card
reading device on which job con-
trol statements and CSERV control
statements are read.
SYSOOO -- Required. Refers to the tape
drive on which a work tape is
mounted.
SYSOPT -- Required if program phases are to
be punched into cards. Refers to
the card punching device on which
the output is to be produced.
SYSLST -- Required if program phases are to
be printed. Refers to the print-
er on which the printed output is
to be produced.
SYSLOG -- Optional. Refers to the printer
on which cont£ol statements, mes-
sages, and information on the
extracted phases may be printed.

The following job control statements are
used to set up the system for the execution
of the CSERV program.

address whose device
assignment in main
storage is to be changed.
Re'luired.
Any other job control statements (such
as FILES or LOG statements) need be issued
only if the corresponding functions are
required.
~he job control statements are read on
the device assigned to SYSRDR.
The following program control statements
are used to supply information to the CSERV
program.

II DSPLY
and
II MONTR
II PUNCH phase-name
Required if the pro-
gram phase whose
name appears in the
operand field is to
be printed.
Required if all pro-
gram phases con-
tained in the core-
image library are to
be printed.
Required if all pro-
gram phases whose
names begin with a
character combina-
tion identical to
that preceding the
period in the
operand field are to
be printed.
Required if the tape
Basic Monitor pro-
gram is to be
printed.
Required if the pro-
gram phase whose
name appears in the
