Frequency Asked Questions
</H1>
<P>
This chapter will serve as a container for questions asked by
some enthusiastic <I><B>MMA</B></I> users. It may make some sense in the future to
distribute this information as a separate file.
<P>
<H1><A NAME="SECTION002210000000000000000">
AABA Song Forms</A>
</H1>
<P>
<I>How can one define parts as part "A", part "B" ...and arrange them at the end of the
file? An option to repeat a ``solo'' section a number of times would be nice as well.</I>
<P>
Using <I><B>MMA</B></I> variables and some simple looping, one might try something like:
<P>
<TABLE CELLSPACING=0 CELLPADDING=5" BGCOLOR="OldLace" BORDER=3><TR> <TD>
<BLOCKQUOTE><B>Groove Swing
<BR>// Set the music into a
<BR>// series of macros
<BR>
mset A
<BR> Print Section A
<BR> C
<BR> G
<BR>
endmset
<BR>
mset B
<BR> print Section B
<BR> Dm
<BR> Em
<BR>
endmset
<BR>
mset Solo
<BR> Print Solo Section $Count
<BR> Am / B7 Cdim
<BR>
endmset
<BR>// Use the macros for an
<BR>// "A, A, B, Solo * 8, A"
<BR>// form
<BR>$A
<BR>$A
<BR>$B
<BR>
set Count 1
<BR>
label a
<BR> $solo
<BR> inc COUNT
<BR> if le $count 8
<BR> goto A
<BR> endif
<BR>$A
<BR></B></BLOCKQUOTE>
</TD></TR></TABLE>
<P>
Note that the ``Print'' lines are used for debugging purposes. We have mixed
the case of the variable names just to illustrate the fact that ``Solo'' is the
same as ``SOLO'' which is the same as ``solo''.
<P>
Now, if you don't like things that look like old BASIC program code, you could just as
easily duplicate the above with:
<P>
<TABLE CELLSPACING=0 CELLPADDING=5" BGCOLOR="OldLace" BORDER=3><TR> <TD>
<BLOCKQUOTE><B>Groove Swing
<BR>
repeat
<BR> repeat
<BR> Print Section A
<BR> C
<BR> G
<BR> If Def count
<BR> eof
<BR> Endif
<BR> Endrepeat
<BR> Print Section B
<BR> Dm
<BR> Em
<BR> Set Count 1
<BR> Repeat
<BR> Print Solo $Count
<BR> Am
<BR> Inc Count
<BR> Repeatending 7
<BR> Repeatend
<BR>
Repeatend </B></BLOCKQUOTE>
</TD></TR></TABLE>
<P>
The choice is up to you.
<P>
<H1><A NAME="SECTION002220000000000000000">
Where's the GUI?</A>
</H1>
<P>
<I>I really think that <I><B>MMA</B></I> is a cool program. But, it needs a <I>GUI</I>.
Are you planning on writing one? Will you help me if I start to write one?</I>
<P>
Well, we appreciate the fact that you like <I><B>MMA</B></I>. We like it too.
<P>
We've actually started to write a number of <I>GUI</I>s for <I><B>MMA</B></I>. But, nothing
seemed to be much more useful than the existing text interface. So, we figured
that it just wasn't worth the bother.
<P>
Now, we are not against graphical programming interfaces. We just don't see it
in this case.
<P>
But, we may well be wrong. If you think it'd be better with a <I>GUI</I> ...well,
this is open source and
you are more than welcome to write one. If you do, we'd suggest that you make
your program a front-end which lets a user compile standard <I><B>MMA</B></I> files. If you
find that more error reporting, etc. is required to interact properly with
your code, let us know and we'll probably be quite willing to make those kind of
changes.
<P>
<H1><A NAME="SECTION002230000000000000000">
Where's the manual index?</A>
</H1>
<P>
We agree that this manual needs an index. We just don't have the time to
go though and do all the necessary work. Is there a volunteer?
<P>
