SUBTTL	COMMAND PARSER AND DISPATCH


;SCAN, PARSE AND REPARS CONSTITUTE THE TOP LEVEL ROUTINES IN TOPS-20 SORT'S
;COMMAND SCANNER. THE FLOW OF CONTROL BETWEEN THESE ROUTINES IS SOMEWHAT
;DICTATED BY THE REST OF SORT AND THE COMND% JSYS, SO THEIR OPERATION IS:
;
;SCAN
;
;SCAN IS CALLED TO READ COMMAND LINES UNTIL A VALID SORT OR MERGE COMMAND IS
;TYPED. SCAN THEN RETURNS TO LET THE REST OF SORT PROCESS THAT LINE. IF THE
;COMMAND SCANNER GETS A TAKE COMMAND, IT REMEMBERS THIS FACT SO THAT WHEN THE
;TOP LOOP CALLS SCAN THE NEXT TIME, THE COMND% STATE BLOCK IS NOT REINITIALIZED,
;BUT STILL POINTS TO THE TAKE FILE.
;
;PARSE
;
;PARSE IS CALLED INTERNALLY WHEN A VALID SORT OR MERGE COMMAND WAS NOT THE LAST
;COMMAND TYPED, AND A NEW COMMAND LINE SHOULD BE READ. THIS HAPPENS IF ONE OF
;THE OTHER VALID COMMANDS WAS TYPED (HELP, TAKE), OR IF A COMMAND SCANNER ERROR
;WAS DETECTED. PARSE THEN EITHER READS ANOTHER COMMAND, OR, IF APPLICABLE,
;RETURNS THE ERROR CODE TO THE FORTRAN SUBROUTINE THAT CALLED SORT. NOTE THAT
;FOR THE ^H FEATURE OF COMND% TO WORK, THE COMMAND STATE BLOCK SHOULD *NOT* BE
;REINITIALIZED HERE. THE .CMINI FUNCTION NEEDS THE OLD TEXT BUFFER POINTERS IN
;THIS CASE, AND WILL DO THE REINITIALIZATION FOR US IF ^H IS NOT TYPED. ALSO, IF
;WE ARE CALLED FROM FORTRAN WITH A STRING, WE MUST CONVINCE COMND% TO USE IT.
;THE ONLY KNOWN WAY IS TO SET THE JFNS TO NUL: (DONE IN SCAN), DO THE .CMINI
;FUNCTION, AND ONLY THEN TELL COMND% THAT THERE ARE A LOT OF UNPARSED CHARACTERS
;THAT JUST HAPPEN TO BE THE USER'S COMMAND STRING (PUT THERE ON ENTRY TO SORT).
;
;ALSO, SINCE PARSE FUNCTIONS AS A CLEAN-UP FOR COMMAND ERRORS AND THE LIKE, WE
;MUST BE PREPARED TO RETURN TO THE CALLER IF WE WERE CALLED BY A FORTRAN
;PROGRAM. THIS RETURN CAN EITHER BE DUE TO AN ERROR, OR THE COMND%'S LIMITATION
;OF ONE COMMAND. THIS IS THE BULK OF THE WORK PRIOR TO ACTUALLY STARTING TO
;PARSE A COMMAND.
;
;REPARS
;
;REPARS IS CALLED FROM PARSE, BUT IS ALSO THE COMND% REPARSE ROUTINE. THEREFORE,
;IT MUST RESTORE SORT'S STATE TO THAT AT THE BEGINNING OF A NEW COMMAND LINE.
;THERE ARE TWO REASONS FOR THIS. FIRST, ON A COMND% REPARSE, WE MUST RE-SCAN THE
;LINE FROM THE BEGINNING. SECOND, ALL COMMAND SCANNING ERRORS EVENTUALLY END UP
;AT PARSE (AFTER PRINTING THE ERROR MESSAGE) SO THAT ANY PARTIAL INFORMATION
;ABOUT THE BAD LINE SHOULD BE DISCARDED. CURRENTLY, ALL THIS INVOLVES IS FREEING
;ANY MEMORY ALLOCATED VIA GETSPC.
;
;FINALLY, REPARSE PARSES THE FIRST FIELD ON THE COMMAND LINE AND CALLS THE
;APPROPRIATE ROUTINE. ONLY THE SORT AND MERGE COMMANDS RETURN, CAUSING REPARS
;TO RETURN TO THE REST OF SORT TO PROCESS THESE COMMANDS. THE OTHERS EITHER
;NEVER RETURN (E.G., RUN) OR 'RETURN' VIA TRANSFERRING TO PARSE.

SUBTTL	SORT/MERGE COMMANDS -- RUN


;This code processes the RUN command. Following successful typein by the user,
;the current core image is replaced with the program to be run, and then the new
;program is started. To do this properly requires a great attention to detail.
;The following roughly describes the algorithm used:
;
;  1.	Process the file specification argument, and finish the command.
;  2.	Convert file specification's file name to SIXBIT for the later SETSN.
;  3.	Determine if the file is from SYS: so system name or '(PRIV)' can be
;	set. This is the bulk of the code. Do this by tacking "SYS:" on the
;	front of just the file specification's name.typ, and do a physical-
;	only GTJFN. Get the full file specification for both the user's program
;	and the one we tried to find on SYS: and compare them. If they match
;	completely, the original file is from SYS:, and we can set the system
;	name. This algorithm guarantees that only the first occurrance of the
;	program on system logical name SYS: qualifies as `from SYS:', since
;	subsystem statistics taken on more than one program are not very valid.
;  4.	Load the final code into the ACs to kill the current core image, bring
;	in the new one, and start it. Final code must execute in the ACs since
;	we have no other core left after the PMAP.
