Print various ways to use Repeat, RepeatEnding and Goto.

Print musical data which mma would produce.

Print This first section shows a simple repeat.
Print

Set Count 1
Print * Introduction
Repeat
	Print ** Repeated Section $Count
	Inc Count
RepeatEnd 3
Print * After repeated section ....

Print
Print Next, we have a repeat section with 2 endings. The
Print first ending is done twice, the second only once.
Print Note that we end up with a total of 4 sections.
Print

Set Count 1
Print * Introduction
Repeat
	Print ** Main Section $Count
	Inc Count
RepeatEnding 2
	Print  **** 1st ending
RepeatEnding 
	Print **** 2nd ending
RepeatEnd 
Print * After repeated section ....

Print
Print This example shows a combination of Repeat and RepeatEnding with a count
Print In this case there are a total of 4 sections. The 1st 2 use the ending,
Print the 2nd 2 don't. Note we use a count of 3 in the RepeatEnd, not 2!!
Print

Set Count 1
Print * Introduction
Repeat
	Print ** Main Section $Count
	Inc Count
RepeatEnding 2
	Print  **** 1st ending
RepeatEnd 3
Print *  After repeated section ....


Print
Print Finally, a complicated example using a DS/Coda. In most cases when 
Print we play a coda section one ignores the repeats. This is done with
Print some handy macros.
Print	

Set Count 1
Set EndingCount 1

Print * Introduction (before repeat and SIGN)
Label Sign
Repeat
	Print ** Main Section $Count
	Inc Count
RepeatEnding $EndingCount
	Print **** RepeatEnding
RepeatEnd
Print * This is after the Repeat
If Def Coda
	Goto Coda
Endif

Print * Song between the ending and coda

// Now we jump back to the sign

Set EndingCount 0
Set Coda
Goto Sign

Label Coda
Print * This is the Coda section

Print Hope all this helps!
