System/310 and 1094 emulator jobs can be intermixed in the OS input
stream, with special processing necessary sometimes for binary format
jobs and data. OS job control and any required 1094 emulator control
statements must be supplied for each 1094 program to be emulated.
Existing 1094 object programs and control statements need not be
modified unless they use facilities not supported by the Model 165
1094 Emulator program.
BCD format 1094 jobs and data can be placed in the input stream
or in a card or tape data set. Binary format 1094 jobs in card form
(object programs and data) can be placed in the input stream (in a
card reader with the column binary feature) in an MVT environment if
the automatic SYSIN batching (ASB) reader interpreter is used. Binary
card input can also be read from a dedicated card reader with the
column binary feature. Required emulator control statements can be
entered via the operator's console or a data set identified by a
specially named DD statement (SYSEMCTL). This data set can be in the
input stream or in a card, tape, or disk sequential data set (including
a member of a partitioned data set).
The 1094 Emulator program operator commands available can be entered
via the operator's console or the input stream (located in the emulator
control statement data set),. These commands provide simulation of
1094 console operations and allow the operator to request dumps of
emulator processor storage areas and to obtain certain displays (sense
switch settings, register values, etc.). If multiple console support
(MCS) is included in the OS control program generated, emulator program
messages can be routed to a specific console device (assigned routing
code 12) so that emulation messages are isolated.
Assuming that the 1094 programs to be emulated do not use facilities
or I/O devices unsupported by the Model 165 1094 emulator, the following
is required:
• OS job control and any required Model 165 1094 emulator control
statements must be supplied for each 1094 object program to be
emUlated. Changes to BCD format data is not required. If binary
card input is not handled by card reader operations, a utility
program must be written to prepare an acceptable tape from the
binary input. A user-written data set writer is required to print
and punch 1094 files written to SYSOUT data sets, if any. (See
