;Macros for defining BUGs
;General format for in-line bug macro call is:
;	BUG. (TYP,TAG,MODULE,WORD,STR,LOCS,HELP,CONTIN)
;
;TYP -	Flavor, HLT, CHK, or INF
;
;TAG -	Name of BUG
;
;MODULE -
;	Name of module in which BUG occurs.
;
;WORD -	Flavor of BUG.  For instance, HARD for hardware-caused, SOFT for
;	software-caused.
;
;STR -	Short descriptive string describing cause of BUG, which gets printed
;	on CTY when BUG occurs.
;
;LOC -	List of locations whose contents should be displayed when the BUG
;	occurs.  Each location must be followed by a comma and then a one-word
;	descriptor of what the datum represents, for instance UNIT or CHN.
;	Each pair of locations and descriptors must be in angle brackets,
;	and the angle-bracketed pairs must be separated by commas with the
;	entire LOC argument in angle brackets.
;
;HELP -	General documentation for the BUG
;
;CONTIN - Optional continuation address after BUGCHK or BUGINF is
;	logged.  Assumed to be in same section with call.
;
;FLAGS - [7.1081] Optional flags for this BUG (only if TYP is CHK or INF)
;	 Should contain DB%NND if BUG is not normally dumpable when we are
;	 dumping all BUGCHKs or BUGINFs.  (DB%NND defined in MONSYM).
