Thank you John!

The inclusion of macros in version 3.48 is just what the doctor ordered for
my increasingly complex orc files.

I would like to see 1 addition however.  In a macro definition, it would be
nice to be able to use a special type of string that gets replaced uniquely
each time the macro is called.

This way, if you call a macro twice in the same instr, they don't share the
same data space for an variable created using the unique-string feature.
This is especially important for k/a-rate variables used in recursion.

This also provides a way to have macros that don't foul the data space of
code outside the macro.

My suggestion is that unique strings be defined as $name$, where name is
like a variable name.

$name$ is replaced by unique# each time a macro is expanded, where # is a
unique index number

This may require variables of the form xunique# to be illegal (reserved) in
normal orchestra syntax.

This is a little more complex than the macroing already implemented, but I
think it shouldn't be too hard to code.

If anyone is interested in this, but is a little confused by what I mean,
e-mail me.  It is hard to talk about macros sometimes due to the abstraction
involved. :)

An example follows:

;*******************Example orc:

#define EXAMPLE(OUT) #
	k$spec$r 0	init	0
	k$spec$r 1	init	0
	k$spec$r 2	init	0
	k$spec$r2	=	k$spec$r1
	k$spec$r1	=	k$spec$r0
	k$spec$r0	=	int(rnd(1000))
	;code using k$spec$r2, k$spec$r1, k$spec$r0 and defining OUT
	#	;end of macro

instr 1

k1	init	0
k2	init	0

EXAMPLE(k1)

EXAMPLE(k2)

;etc.
;**********************Parsed orc:


instr 1

k1	init	0
k2	init	0


	kunique1r 0	init	0
	kunique1r 1	init	0
	kunique1r 2	init	0
	kunique1r2	=	kunique1r1
	kunique1r1	=	kunique1r0
	kunique1r0	=	int(rnd(1000))
	;code using kunique1r2, kunique1r1, kunique1r0 and defining k1



	kunique2r 0	init	0
	kunique2r 1	init	0
	kunique2r 2	init	0
	kunique2r2	=	kunique2r1
	kunique2r1	=	kunique2r0
	kunique2r0	=	int(rnd(1000))
	;code using kunique2r2, kunique2r1, kunique2r0 and defining k2
