Begin/End Blocks
</H1>
<P>
Entering a series of directives for a specific track can get quite
tedious. To make the creation of library files a bit easier, you can
create a block. For example, the following:
<P>
<Table Hspace="40%" CellSpacing=0 CellPadding=10 BGColor="OldLace" Border=3>
<tr><td>
<B>Drum Define X 0 2 100; 50 2 90
<BR>
Drum Define Y 0 2 100
<BR>
Drum Sequence X Y </B>
</td></tr>
</Table>
<P>
Can be replaced with:
<P>
<Table Hspace="40%" CellSpacing=0 CellPadding=10 BGColor="OldLace" Border=3>
<tr><td>
<B>Drum Begin
<BR> Define X 0 2 100; 50 2 90
<BR> Define Y 0 2 100
<BR>
End
<BR>
Drum Sequence X Y </B>
</td></tr>
</Table>
<P>
Or, even more simply, with:
<P>
<Table Hspace="40%" CellSpacing=0 CellPadding=10 BGColor="OldLace" Border=3>
<tr><td>
<B>Begin Drum Define
<BR> X 0 2 100; 50 2 90
<BR> Y 0 2 100
<BR>
End </B>
</td></tr>
</Table>
<P>
If you examine some of the library files you will see that this
shortcut is used a lot.
<P>
<H1><A NAME="SECTION003010000000000000000">
Begin</A>
</H1>
<P>
The B<SMALL>EGIN</SMALL> command requires any number of arguments. Valid
examples include:
<P>
<Table Hspace="40%" CellSpacing=0 CellPadding=10 BGColor="OldLace" Border=3>
<tr><td>
<B>Begin Drum
<BR>
Begin Chord2
<BR>
Begin Walk Define </B>
</td></tr>
</Table>
<P>
Once a B<SMALL>EGIN</SMALL> block has been entered, all subsequent lines have
the words from the B<SMALL>EGIN</SMALL> command prepended to each line of
data. There is not much magic here--B<SMALL>EGIN</SMALL>/E<SMALL>ND</SMALL> is really
just some syntactic sugar.
<P>
<H1><A NAME="SECTION003020000000000000000">
End</A>
</H1>
<P>
To finish off a B<SMALL>EGIN</SMALL> block, use a single E<SMALL>ND</SMALL> on a line
by itself.
<P>
Defining musical data or repeats inside a block
(other than COMMENT blocks) will not work.
<P>
Nesting is permitted, e.g.:
<P>
<Table Hspace="40%" CellSpacing=0 CellPadding=10 BGColor="OldLace" Border=3>
<tr><td>
<B>Scale Begin
<BR> Begin Define
<BR> </B><SPAN CLASS="textit">stuff</SPAN><B>
<BR> End
<BR> Sequence </B><SPAN CLASS="textit">stuff</SPAN><B>
<BR>
End </B>
</td></tr>
</Table>
<P>
A B<SMALL>EGIN</SMALL> must be competed with a E<SMALL>ND</SMALL> before the end of a
file, otherwise an error will be generated. The U<SMALL>SE</SMALL> and
I<SMALL>NCLUDE</SMALL> commands are not permitted inside a block.
