For VAX users looking over the SYMBOLS.CMD file, you need to know
only the following:

1)  Sequences like:

	.setd $bel
	.setn $bel	7.
	.sets bel	"'$bel%v'"
	.erase symbol $bel

   are indicative of the terrible gyrations you have to go through to
   do the VMS DCL equivalent of:

	$ bel[0,7]== 7

2)  Lines like:

	.sets PF1	"'ss3'P"
	.sets f6	"'csi'17~"
	.sets revers	"'csi'7m"	;; set character reverse video on

   would be written in VMS DCL as:

	$ PF1==     "''ss3'P"
	$ f6==      "''csi'17~"
	$ reverse== "''csi'7m"

3)  A subroutine like:

	.;--------------------------------------------------------------
	.; Scroll:  set the scroll region, given top and bottom margins.
	.;
	.; call as:  .gosub Scroll TopRow,BotRow
	.;--------------------------------------------------------------

	.Scroll:

		.parse comman "," top bot

		.disable quiet
	;'csi''top%c';'bot%c'r
		.enable quiet

		.return

   could be written as:

	$ Scroll:	subroutine
	$ !!
	$ !!------------------------------------------------------------
	$ !! Set the scrolling region, given top and bottom margins.
	$ !!
	$ !! Call as:  call Scroll top_row_number bottom_row_number
	$ !! Example:  call Scroll 4 20
	$ !!------------------------------------------------------------
	$ !!
	$ write sys$output "''csi'''p1';''p2'r"
	$ !!
	$ endsubroutine
