Input Dump Record2
Dump Record 1
Notes
1 Print the heading line which contains
the time, date, abend code and cause.
2 Unpack the general registers and the control registers by branching and I !inking to the transmit routine, move I the data by branching and linking to
the MVSB RTN routine and print it
by branching and linking to the PRINTA routine.
3 Print the floating point registers as
in Step 2, above.
4 Unpack and print the TOD clock, clock comparator and CPU timer as
in Step 2, above.
5 Translate low storage and format and
print the PSWs. 6 If NOMAP was omitted, print the symbol table. From Processing

1 Format and print the following real
control blocks: • RCHBLOKs and IOBLOKs chained
to them • RCUBLOKs and IOBLOKs chained
to them • RDEVBLOKs • Active IOBLOK • RSPLCTL and SFBLOK for unit
record devices • CONT ASK for termination • RECBLOKs for CP owned DASD
devices
Branch and link to the following
routines for commonly used functions: GETPAGE To get a page of storage. TRANINIT To translate control
blocks into printable
form. BLKPRINT To print real control
blocks. IOBPRINT To print IOBLOK. SFPRINT To print SFBLOK. IOERPRINT To print IOERBLOK. 2 Print the printer, reader, and punch SFBLOK chains.
Note: PRTSPL points to the punch
spool and RDRSPL points to the
reader spool.
