THE CPLOAD MAP WILL AUTOMATICALLY BE PRINTED AT'THE PRINTER WHOSE ADDRESS IS 'OOE'. IF THERE IS NO PRINTER AT THIS ADDRESS THE LOAD MAP WILL BE PRINTED AT
THE FIRST PRINTER CAUSING AN INTERRUPT, (IE. NeT-BEADY TO READY SEQUENCE). ONCE THE NUCLEUS HAS BEEN LeADED, YOU MAY IPL YOUR NEW CP SYSTEM RESIDENCE VOLUME. NOTE: THERE MUST BE ENOUGH STORAGE ON THE SYSTEM (VIRTUAL OR
REAL), TO CONTAIN THE VIRT=REAL AREA AND THE CP NUCLEUS. Figure 7-11. GENERATE Messages (Part 3 of 3) 160 IBM VMj370 Service Routines Program Logic

DMKLDOOE (LOADER) PROGRAM If the loader terminates, one of the
following wait conditions is indicated in
the instruction counter:
Code 1'111111' X'222222' X' 999999' X'BBBBBB' X'CCCCCC' X'FFFFFF' !1!anij!g A program check occurred.
1 unit check occurred while the
bootstrap routine was reading
in the loader. An SVC was issued. A machine check occurred. An I/O error occurred on the card reader: An I/O error occurred for the
console (X'OO' contains the
message UBRECOVERABLE ERROR),
or the control card for
changing the default I/O addresses for the printer or
terminal is invalid (X'OO' contains the message BAD DEVICE CARD or INVALID DEVICE SPECIFIED). LOADER WAIT STATE CODES If the instruction counter contains X'999999', indicating an SVC wait state,
examine the interruption code (the third
and fourth bytes of the supervisor old PSi). The interruption codes (shown in
hexadecimal) have the following meanings:
Code 64 65 66
61 68 65 61 6E 6C 6I Meaning An error occurred during conversion
of a value from hexadecimal to
binary format.
There is no aore free storage
available for the loader. A duplicate type 1 ESD (External Symbol Dictionary) entry has been
encountered.
The "name" in the LDT (Loader
Terminate) statement is
undefined.
The control section named in the les (Include centrol Section) statement was not fcund by end of
file.
The loader attempted to add another
entry to the reference table,
which would have caused the table
to overflow.
The object modules being loaded are
about to overlay the loader.
The object modules being loaded are
about to overlay an address
between zero and laO. 1 permanent errcr occurred in the
input device.
The loader is trying to release
storage that is not cn a doubleword boundary. For further explanations cf these wait
state conditions and the recommended
operator action to correct thea, see !!L170 Chapter 7. Procedures for Generating and Cpdating V!/310 161
