IBM System/360 20 User Manual

The l'lacro Service r-rogram (MSERV) enables
the user to check individual macro defini-
tions or the complete contents of the macro
library on his system tape. It also
enables him to punch out some or all of the
contents of the library for such purposes
as making corrections or creating backup.
The program is used to print one, sever-
al, or all of the macro definitions from
the library, the listing being in the same
form (i.e. one caJ:d per line) as the ori-
ginal cards, and/oJ: to punch the macro
definitions into cards.
Output from the MSERV program may be
used as input to the Macro Maintenance
program.
I/O DEVICE ASSIGNMENTS
The following symbolic device addresses are
used in preparing and performing the execu-

SYSRES -- Required. Assigned at IPL time.
Refers to the tape drive on which
the system tape is mounted.
SYSRDR -- Re1uired. Refers to the card
reading device on which job con-
trol statements and MSERV control
statements are read.
SYSOOO -- Required. Refers to the tape
drive on which a work tape is
mounted.
SYSOPT -- Required if macro definitions are
to be punched into cards. Refers
to the card punching device on
which thE! 0 utp ut is to be
produced.
SYSLST -- Required if macro definitions are
to be printed. Refers to the
printer on which the printed out-
put is to be produced.
SYSLOG -- Optional. Refers to the printer
on which oontrol statements, mes-
sages, and information on the

II EXEC
l'lSERV Required.
Re~uired if the execution
of the MSERV program is
the first job in a system
run.

definitions in the macro
library are to be
frinted.

definitions in the macro
library are to be
punched.
II tSFCH macro- Required if the macro
name definition whose name
appears in the operand
field is to be both
printed and punched.

definitions in the macro
library are to be both
printed and punched.
