CAUTION
Do not use class-R packs as scratch packs
when generating new libraries. Auxiliary
libraries, however, may reside on class-R
packs.
8.1 LOADING AND EXECUTION
PRELIB uses all of available memory.
It
may be run while a priority program is in
execution.
The PRELIB user must be familiar with the PRELIB source deck supplied
for installation.
PRELIB detail cards (PDC) are binary cards for the relocatable programs to be placed
on the new library.
Each deck must begin with an IDC card and end with a TRA card.
8.2 PRELIB CONTROL CARDS
PRELIB control cards (PCC) direct PRELIB in the generation of a new library.
They
allow addition and deletion of records and entry points.
Unlike MSOS control cards,
PRELIB control cards must begin with ~; a
$
is not allowed.
8.2.1 PRELIB
The user loads PRELIB into core with the PRELIB statement.
When JOBCTL en-
counters a PRELIB card, it calls LOADER to load PRELIB and its overlays and seg-
ments from file 2 of the library.
JOB, EQUIP. and other required MSOS control cards
precede the PRELIB card.
MSOS gives control to PRELIB, which reads the PRELIB binary source file or PRELIB
I
control statements from INP or from the I=lun unit.
PRELIB executes automatically
when called; a RUN card is not needed.
There are two formats of the PRELIB control
card.
If modifications are to be made to the main library, it has the following format.
