To punch the required job stream for stage I execution to the as/vs
machine's virtual card reader, enter the following commands:
cp specl punch to osvssys cont punch stglin ojcl (noheader)
punch stglin assemble (noheader)
cp spoel punch nocont
cp close punch
By using the CONT operand in the SPOOL PUNCH command, a user
cencatenates multiple CMS files into one punch output file.
If, at the OS/VS machine, a user enters this CP command before
executing stage I: Icp spcel punch to oscms
and subsequently enters: Icp close punch VM/370 transfers the stage I output to the OSCMS virtual card reader. At the OSCHS terminal, issue this command:
readcard stglin text
This CMS file corresponds to the punched output of the stage I assembly
(STG1IN TEXT) performed in the OSCMS machine. VM/370 directs the
assembly listing, output, in the absence of any printer spooling te the real STAGE II PROCESSING The stage I output is a job stream that contains a number of individual
jobs. These jobs set up system data sets, assemble nucleus modules, and
copy modules from the distribution libraries to the new system residence
volume.
If the three object module utility data sets used by the assembler
during stage II have not been allocated and cataloged, a user can do
this by creating the appropriate job stream as a CMS file. Give it a
unique filename, such as STG2IN DSALLOC. To transfer the stage II input to the OS/iS machine, issue these commands: cp specl punch to osvssys cont punch stg2in dsalloc (noheader)
punch stg1in text (noheader)
cp speel punch nocont
cp close punch
Section 4. OS/VS in a Virtual Machine 123

Process the stage II inFut job stream on the OSVSSYS virtual machine.
Tc enhance this virtual machine's performance, use the various V8/370 oPtions. such as runninq in the virtual=real area and nsing
favored execution with a guaranteed-percentage of processor time. While the OSCftS virtual machine is not directly involved in the stage
II processing, it can be used to subdivide the stage I output into
individual job streams. This subdividing may make it easier to restart
stage II, if necessary.
FINAL HOUSEKEEPING The new system residence volume now contains the new system control Frogram. Add program products in separate runs by following the
procedures contained in the appropriate program product publications. Use the OSCftS virtual machine to set up or .odify job streams used to
test programs, even if these program aren't part of the installation
verification Frocedure supplied with the system control program. Sample OS/VS Directory Entries
