<P>Suppose you're feeling lazy and you want to unroll a time consuming loop. <B>REPT</B> is here for that purpose. Everything between REPT and ENDR will be repeated a number of times just as if you done a copy/paste operation yourself<BR>
<BR>
<TABLE BORDER=0 BGCOLOR="Black" CELLPADDING=8 WIDTH="50%">
<TR>
<TD><FONT COLOR="#00FF00">
<PRE>REPT 4
add a,c
ENDR</PRE>
</FONT></TD>
</TR>
</TABLE>
<P>This will assemble <B>add a,c</B> four times.<BR>
<P>You can also use REPT to generate tables on the fly:
<TABLE BORDER=0 BGCOLOR="Black" CELLPADDING=8 WIDTH="50%">
<TR>
<TD><FONT COLOR="#00FF00">
<PRE>; --
; -- Generate a 256 byte sine table with values between 0 and 128
; --
ANGLE SET 0.0
REPT 256
DB (MUL(64.0,SIN(ANGLE))+64.0)>>16
ANGLE SET ANGLE+256.0
ENDR</PRE>
</FONT></TD>
</TR>
</TABLE>
REPT is also very useful in recursive macros and as in macros you can also use the special label operator \@. REPT-blocks can be nested.<BR>
