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 CELLSPACING=0 CELLPADDING=5" BGCOLOR="OldLace" BORDER=3><TR> <TD>
<BLOCKQUOTE><B>Drum Define X 0 2 100; 50 2 90
<BR>
Drum Define Y 0 2 100
<BR>
Drum Sequence X Y </B></BLOCKQUOTE>
</TD></TR></TABLE>
<P>
Can be replaced with:
<P>
<TABLE CELLSPACING=0 CELLPADDING=5" BGCOLOR="OldLace" BORDER=3><TR> <TD>
<BLOCKQUOTE><B>Drum Begin
<BR> Define X 0 2 100; 50 2 90
<BR> Define Y 0 2 100
End
<BR>
Drum Sequence X Y </B></BLOCKQUOTE>
</TD></TR></TABLE>
<P>
Or, even more simply, with:
<P>
<TABLE CELLSPACING=0 CELLPADDING=5" BGCOLOR="OldLace" BORDER=3><TR> <TD>
<BLOCKQUOTE><B>Drum Begin Define
<BR> X 0 2 100; 50 2 90
<BR> Y 0 2 100
<BR>
End </B></BLOCKQUOTE>
</TD></TR></TABLE>
<P>
If you examine some of the library files you will see that we use this shortcut a lot.
<P>
<H1><A NAME="SECTION001810000000000000000">
Begin</A>
</H1>
<P>
The <I>Begin</I> command requires any number of arguments. Valid examples include:
<P>
<TABLE CELLSPACING=0 CELLPADDING=5" BGCOLOR="OldLace" BORDER=3><TR> <TD>
<BLOCKQUOTE><B>Begin Drum
<BR>
Begin Chord2
<BR>
Begin Walk Define </B></BLOCKQUOTE>
</TD></TR></TABLE>
<P>
Once a <I>Begin</I> block has been entered, all subsequent lines have the words from the <I>Begin</I> command prepended to each line of data. There is not much magic here--<I>Begin</I>/<I>End</I> is really just some syntactic sugar.
<P>
<H1><A NAME="SECTION001820000000000000000">
End</A>
</H1>
<P>
To finish off a <I>Begin</I> block, use a single <I>End</I> on a line by itself.
<P>
Defining musical data, repeats, or other <I>Begin</I>s inside a block (other than COMMENT blocks) will not work.
<P>
Nesting is permitted. Eg:
<P>
<TABLE CELLSPACING=0 CELLPADDING=5" BGCOLOR="OldLace" BORDER=3><TR> <TD>
<BLOCKQUOTE><B>Scale Begin
<BR> Begin Define
<BR> </B></BLOCKQUOTE><I>stuff</I><BLOCKQUOTE><B>
<BR> End
<BR> Sequence </B></BLOCKQUOTE><I>stuff</I><BLOCKQUOTE><B>
<BR>
End </B></BLOCKQUOTE>
</TD></TR></TABLE>
<P>
A <I>Begin</I> must be competed with a <I>End</I> before the end of a file, otherwise an error will be generated. The <I>Use</I> and <I>Include</I> commands are not permitted inside a block.
