00100	COMMENT ⊗  SWITCHES : AN INTRODUCTION
00200	Conditional assembly runs rampant in SAIL.  Most of the switches are used to
00300	 select options (debug or no debug, etc.) Some are only valid at Stanford.
00400	 There is one, EXPORT, tested by the macros NOEXPO and EXPO, which decides
00500	 whether this is for Stanford or somebody else.
00600	
00700	We have a program which, by reading the SAIL files and looking for switch-
00800	 testing macros, can do the conditional assembly once and for all (removing
00900	 the conditional stuff from the files.  It is such a set of files which
01000	 we normally send out, so if you see some switches and macros below that
01100	 never get referenced, it's because that code was taken out of your files.
01200	
01300	The conditional assembly switches are assigned in the following files:
01400	
01500	DCS	DCS	←2				;SLS (experimental) system
01600		FTDEBUG ←1				;include debugging in cmplr
01700	
01800	;NOCOM	COM2SW	←0				;OBSOLETE SWITCH, WAS TO

02600		HEDSYM	←if NDEF then 0 else HEDSYM	;With HEDSYM on, assembling HEAD
02700							; yields HEAD.REL, a symbol
02800							; file for the USERCON function

06200		LOADVR  ←if NDEF then 54 else LOADVR (for differences in block code
06300				for required rel files,libraries in LOADER 54)
06400		 SAILRUN was a switch controlling some runtimes.  Now runtimes will
06500		  be assembled to assume a compiler (since that's common anyway).

00300	These macros come in pairs, and exist so that the above-mentioned
00400	 program will have an easy job of it.  The meaning of each pair is
00500	 obvious.  They may be used only as in the following example:
00600	SW <			;or NOSW, starting in col. 1 (any comment out here)
00700	(code to appear under this switch)
00800	>;SW			or NOSW, must be same, any comment out here

00100	DSCR USER DATA AREA TEMPLATE  
00200	DES These values serve as indices for the run-time routines
00300	  into the user's data table. The table is necessary to allow
00400	  the routines to be re-entrant.  The table is allocated
00500	  in the SAILOR sequence at startup time; many of its values
00600	  (data area bounds, etc.) are placed in it at that time.
00700	 One can force re-initialization of this and all other dynamic
00800	  areas by setting GOGTAB to 0 before next CORGET.
