; - In STCRJB, return Global job number to CRJOB creator, put index in JOBONT
; - In RUNDD3, Initialize CFS Global Job Number database...
; - In HSYS41:, convert local job index to global job number for LGOUT Jsys
; - In LOG2, call JBAVAL to release Global job number just before HLTJB call.
; - In LOGJOB, Print Global job number during logout.
; - In ELOGO, translate user-specified global job number into local index
; - In .GJINF, use GBLJNO to return user's own job number, instead of JOBNO
; - In .GETAB, overhaul GTTAB table to use new GTJOB routine to translate
;   user-specified Global Job number into local job index.  Make the tables'
;   'size' be the highest legal Global Job number, MXGLBS, for range checking
;   instead of NJOBS, which is only the highest index value.
;   Also, create jacket routine TTY2GL to convert job index returned by
;   GTBTTF to a global job number
; - In .GETJI, translate user-specified global job number into local index
; - In GETJI4, translate job index into Global job number before returning it.
; - In GETJIT table, return other jobs Global Job number (from JSB)
; - In ATACH1, same as .GETJI

Cause:	An attempt to log in/out a job has failed when it should have succeded.
	The most likely cause of this is terminals that have been TTYSTPed,
	then a LGOUT or LOGIN JSYS was attemped.  An attempt to detach the
	terminal, then logout the job is made.  If either of these fail,
	the job is put in a permanent wait state.

Action:	None.

Data:	The terminal number, and the reason of the failure.

Cause:	An unexpected error has occurred in Job 0 which results
	in control being transferred to the default error handler.
	This has happened during job 0 initialization.
	The error handler will attempt to reset the context and
	continue at the specified error address,
	however some system resources may be
	hung as a result of locks not being cleared.  The stack
	can be examined to determine what was in progress when
	the error occurred.

Data:	1. PC at which error occurred.
	2. Address to which control will be transferred after cleanup.
	3. Last error code in this fork.

Cause:	When a software channel 34 or 35 interrupt happens on fork
	0, the monitor transfers control to the routine specified in
	MONBK.  This address will often be the starting address of
	JB0INT.  JB0INT handles errors in fork 0.  While JB0INT is doing its
	error recovery, it sets MONBK to J0EMER, so that this STRTER BUGHLT
	will occur if another error happens during JB0INT execution.

; Note, job tables are accessed by Job index, which must be translated

		 BUG.(HLT,UXXCKP,MEXEC,soft,<COULDN'T CREATE CHECKPOINT FILE>,,<

Cause:	The file PS:[ACCOUNTS]CHECKPOINT.BIN.1 could not be referenced
	for one reason or another.  The code first attempts a GTJFN (GJ%PHY,
	GJ%OLD) and an OPENF (OF%RD,OF%WR,OF%RTD), one of which must fail
	for UXXCKP to be a possibility.

	After the above GTJFN or OPENF has failed, then a GTJFN (GJ%PHY,GJ%NEW)
	is attempted.  If this succeeds, then UXXCKP will occur if a failure
	happens on one of the following: the subsequent OPENF (OF%WR,OF%RD),
	the call to ASGSWP to allocate CKPSIZ words, or the SOUT writing
	CKPSIZ words to the checkpoint file.

	If the GTJFN (GJ%PHY,GJ%NEW) fails, then another GTJFN (GJ%PHY,GJ%DEL)
	is attempted, and its failure will cause UXXCKP.  If this GTJFN
	succeeds, however, then a CHFDB (turning off FB%DEL to undelete the
	file) is done, and its failure will also cause UXXCKP.

Action:	Use EDDT to patch the system so that you can bring up the system
	without the checkpoint file being referenced.  Then get the checkpoint
	file into a state such that none of the above failures will occur.

	It calls JFNOFN to convert the JFN.PN atom to OFN.PN, which SETMPG

	will fail are: JFN is not associated with a disk file; JFN is not open;
	attempt to create a new page table for a file that is not open for
	writing; attempt to create a new page table for a directory file;
	attempt to create a new page table for which there is no room on disk.
