***** Begin Revision History *****

1	-----	-----	FIX CREFIT TO CREF INCLUDED FILES EVEN IF THEY
			ARE NOT LISTED

			LOWER THE VERBOSITY LEVEL OF ERRORLESS PROGRAMS

2	-----	-----	PUT [NO ERRORS DETECTED] ON LISTING BUT NOT TTY

3	-----	-----	CREF - CHANGE ^G TO ^Q SO VERSION 51 WILL RUN
4	747	-----	MAKE ALL STRINGS LOWER CASE FOR PRINTOUT

***** Begin Version 6 *****

5	760	TFV	1-Mar-80	-----
	Use singular for 1 warning and/or 1 error

6	1047	EGM	22-Jan-81	Q10-05325
	Add support for TOPS-10 execute only.

7	1133	TFV	28-Sep-81	------
	Add routines STATS and OUTTIME for /STATISTICS output.
	Print out size of generated code and data, runtime, connect time,
	and dynamic memeory used by the compiler.

***** Begin Version 6A *****

1160	EGM	14-Jun-82
	Set 'fatal errors this compile command' flag if any fatal errors.

***** Begin Version 7 *****

1526	AHM	12-Apr-82
	Don't subtract CHDSTART from HILOC in STATS because relocation
	counters don't have their origins added into them anymore.

1563	PLB	18-Jun-82
	Change ZZOUTMSG for native TOPS-20 operation
	to use TTYSTR instead of TTCALL.

1633	TFV	1-Sep-82
	Improve  /STATISTICS  to  print  source  lines  per  minute  and
	executable statements per minute.

***** End V7 Development *****

1731	TFV	10-Mar-83
	Fix calls to  ZZOUTMSG in  STATS. Routine  STATS calls  ZZOUTMSG
	with a UPLIT.  ZZOUTMSG tries to modify the PLIT which is in the
	hiseg causing a memory protection failure.

***** End Revision History *****

***** Begin Version 10 *****

2447	PLB	10-Aug-84
	Changes for nested INCLUDE files; SAVFLG is now a vector
	indexed by EXTERNAL ICLEVEL.
