RSCS Generation Procedure Next, format the RSCS system disk again. You must use the recompute
function of the FORMAT command to make the last cylinders of the RSCS system disk unavailable to the CMS file system. The last one or two
cylinders contain the RSCS nucleus. If the RSCS system disk is a 2314
or 3340, the last two cylinders are needed for the nucleus. For a 3330 or 3350, only the last cylinder is needed. The FORMAT command for a
2314 or 3340 RSCS system disk is:
format 195 a 3 (recomp
The FORMAT command for a 3330 or 3350 RSCS system disk is:
format 195 a 4 (recomp STEP 4. CREATE THE COpy FILES THAT DEFINE YOUR RSCS SYSTEM the Editor to AXSLINKS, LAXLINES, and TAGQUEUE. The macros you need to
these files are described in a preceding section, "Defining System." YOu need: include in Your RSCS When you code the GENLINK macros for the AXSLINKS COpy file, you may
include GENLINK macros with no operands. These macros reserve extra
link table entries which can be defined later with the RSCS DEFINE
command. Also, the local linkid (local location ID) must be specified
on the first GENLINK macro in the AXSLINKS file. When you code the GENTAGQ macro for the TAGQUEUE COPY file, remember
that the total number of tag slots must be equal to or greater than the
number of holdslots defined either explicitly or implicitly in the AXSLINKS COpy file.
The following example shows the creation of the AXSLINKS, LAXLINES, and TAGQUEUE COPY files:

called DMTLOC MACLIB, as follows:
maclib gen dmtloc axslinks laxlines tagqueue
If you must change your RSCS configuration at a later time, you have
to change the COpy file and then generate a new DMTLOC macro library. STEP 6. ASSEMBLE THE CONFIGURATION TABLE (DMTSYS) Before you assemble the configuration table module, access the staging
area disk (194) as an extension of the RSCS system disk.
access 194 b/a DMSACC7231 B (194) RIO NOw, assemble the RSCS configuration table module (DMTSYS) using the VMFASM EXEC procedure. Specify DMTRnO as the control file. This
control file identifies DMTLOC as the macro library to be used during
the assembly. The DMTRnO control file is on the 194 minidisk. Invoke VMFASM as follows: VMFASM DMTSYS DMTRnO If an error occurs due to an incorrectly coded macro, correct the
macro and restart at Step 5. Part 3. Generating VM/370 (CP, CMS, RSCS, and IPCS) 285
