It must be the last macro in the CMS file you are building as input to
Stage 1. SPECIAL MACRO CODING CONSIDERATIONS FOR THE EMULATION PROGRAM (EP) There are no strict dependencies between the host access method and the
emulation program; consequently, few guidelines are necessary for an
emulation program generation. However, be careful when configuring
emulator lines for CPT-TWX terminals. While VM/370 normally accepts
incoming calls from either 1050 or 2741 terminals on the same physical
line, that same line cannot be used for CPT-TWX terminals. When generating the VM/370 system, ensure that the hardware configuration in DMKPIO configuration of Emulation Program for CPT-TWX lines; the exact configuration of 1050 and
2141 lines is not critical. Nole: The base address of the 3704/3705 (the address used to load and/or
dump the control program) can never be specified for use as a
telecommunications line. VM/370 treats the base address as a separate
entity for use only during the load and dump operation.
Step 5. Define the Macro and Text libraries
The macro and text libraries created from the distribution tape in Step
3 must be made available to CftS. One macro library (GEN3705) is needed
for the Stage 1 generation procedure and one macro library (MAC3705) and
one text library (OBJ3705) are needed for the Stage 2 generation
procedure. It is easiest to define all the libraries before starting
Stage 1. Use the CMS GLOBAL command:
global maclib gen3705 mac3705
global txt lib obj3705 302 VM/370 Planning and System Generation Guide

step 7. 1 generation procedure accepts the CMS file you created in
input and produces the stage 2 input file that is needed in
The stage 1 generation procedure is performed by invoking the 3105 Assembler to process the 3104/3105 control program macro instructions.
It produces one file with the same filename as the input file and with a
filetype of TEXT. This TEXT file contains 3105 Assembler source
statements and job control language (JCL) statements. THE ASM3705 COMMAND Use the CMS ASM3105 command to invoke the 3105 Assembler to assemble the
macro instruction file. The 3705 Assembler processing and output are
controlled by the options selected. The format of the ASM3705 command
is:

This source file contains the 3704/3105 control program macro
instructions. The file must have a filetype of ASK3105 and
fixed-length, SO-character records.
