EKKO command summary.
			=====================

command         

$!remarks!	"!" -- a remark, ignored -- to allow documenting command
$#		"#" -- print %
$$		"$" -- print $
$%NAME%		"%" -- print variable as a literal, same as $=NAME= but usable
			where "=" not allowed.  Use $=name= in batch file or
			in 4DOS command line.  Use this version in a variable
			to be expanded later where "=" is not allowed.
$'		"'" -- print " (quote).  Useful in 4DOS where unmatched
			double-quotes are not allowed -- replace the unmatched
			quote in an EKKO statement with $'.  Also prevents
			redirection problems when double-quote is present.
$(		"(" -- redirect output to COM1
$)		")" -- cancel ekko redirection
$*		"*" -- screen-dump (except disabled in Sanyo version)
$+		"+" -- set bit 7 of output (with exceptions)
$,		"," -- terminate ekko with cr,lf
$-		"-" -- cancel $+
$/d		"/" -- print path for drive d
$0		"0" -- clear screen.  Colour set by $Uhh.
$;		";" -- terminate ekko without cr,lf at end
$=NAME=		"=" -- print variable as a literal, same as $%NAME% but usable
                       where "%" not allowed
$@nnc		"@" -- Cursor control.  nn is optional decimal parameter
			If screen scrolls, colour for new lines are set
			by a preceding $Uhh.
	$@nnA		"A" -- A is for Advance (can force scroll)
	$@nnB		"B" -- B is for Back Up (can force scroll)
	$@nnD		"D" -- D is for Down
	$@nnH		"H" -- H is for Horizontal position
	$@nnL		"L" -- L is for Left (can't force scroll)
	$@nnO		"O" -- O is for Origin (home cursor, H was taken)
	$@nnR		"R" -- R is for Right (can't force scroll)
	$@nnT		"T" -- T is for Tab (can force scroll)
	$@nnU		"U" -- U is for Up
	$@nnV		"V" -- V is for Vertical position
$Ahh		"A" -- sends hex. byte to ANSI driver (if present)
$B		"B" -- prints |
$Chh		"C" -- sends hex. byte to COM1
$D		"D" -- prints Date, format can be user defined
$E		"E" -- prints ESC character
$G		"G" -- prints >
$H		"H" -- destructive backspace (bs,space,bs)
$J		"J" -- clear screen, same as $0
$L		"L" -- prints <
$N		"N" -- prints current drive letter
$O		"O" -- cursor to Origin, same as $@nnO
$P		"P" -- prints current Path for current drive.
$Q		"Q" -- prints =
$Rnndttttd	"R" -- Repeats text, "tttt" delimited by "d" for "nn" times.
$S		"S" -- prints a Space.  For 4DOS users, this may have to
			be the first printable item on the line if you wish
			to print leading spaces as 4DOS deletes leading
			spaces from the command line.  An initial "$s" for
			the first space will prevent the loss of the leading
			spaces.
$T		"T" -- prints the Time (format user definable)
$Uhh		"U" -- defines attribute to Use with BIOS screen output
			commands: ($0, $@nnA (if scroll), $@nnB (if scroll),
				   $@nnT (if scroll), $Yhh, $Zhh)
			If $Uhh does not precede these commands, a default
			colour of low-intensity white on black is used.
$V		"V" -- prints DOS Version
$Whh		"W" -- prints (Writes) hex. byte to LPT1
$Xhh		"X" -- prints hex. byte to current output
$Yhh		"Y" -- prints hex. byte to screen as a literal (no control
                       action) (same as "$Zhh$@A")  Colour set by $Uhh.
$Zhh		"Z" -- pokes hex. byte to screen without cursor advance.
			Colour set by $Uhh.
$[		"[" -- redirects output to ANSI driver (CON) bypassing
			any printer echoing due to ^P
$\d		"\" -- print path for drive d, same as $/d
$]		"]" -- cancel ekko internal redirection
$^c		"^" -- print character c as control character (turn off bits
			5 and 6).  Not recommended with 4DOS, use $Xhh instead.
$_		"_" -- print cr,lf pair
${		"{" -- redirect output to LPT1
$}		"}" -- cancel ekko internal redirection
%name%		"% %" -- print environment variable, expand ekko commands 
			in variable.  Use %%name%% in batch file or in
			4DOS command line.
%name=%		"% =%" -- print environment variable, expand only those
			ekko commands also supported by PROMPT.  Use
			%%name=%% in batch file or in 4DOS command line.
