Required by the BUILD macro, but does not
apply to VM/370. Specify a valid dsname. IVM/370 recommends I JOBCARD=YES for EP. VM/370 requires that the value of NEWNAME be
the same as the name previously specified
in the NAMENCP macro and the name that
subsequently will be specified in the SAVENCP command. Also, if the GEN3705 command is to be issued with the SAVE option, the value of NEWNAKE must be the
same as the "fname" specified on the
GEN 3705 command. VM/370 requires the default value. VM/370 ignores these operands.
Figure 32. BUILD Macro Operands for VM/370 CSB MACRO INSTRUCTION The CSB macro instruction is required. See the J70! 1105 Generation
and for more information about coding the CSB macro
instruction. GROUP AND LINE MlIf"'On u.Q""'.I.\V INSTRUCTIONS These macros describe the physical and logical configuration of the
communications network accessed through the 3704/3705 control program. Since VM/370 does not support either multi-drop lines or cluster control
units, the 3704/3705 configuration for VM/370 is generally simple, with
only one GROUP macro for each communications scanner. For VM/370, it is
often easiest to specify most of the operands of the LINE macro on the GROUP macro. The l1Q! 1105 Generation and Guide describes
the GROUP and LINE macro instructions in detail and lists all the
operands of the configuration macros, telling you where each operand is
described and also where it may be coded. VM/370 requires the DUPLEX and FEATURE operands. These operands
allow V"/370 to detect and respond to a terminal attention interrupt and
to recognize when a data set has been hung up. For the GROUP macro, VM/370 requires the default value for the REPLYTO operands and
recommends the default value for the TEXTTO operand. Part 4. Generating the 3704/3705 Control Program 301

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
