Everything between REPT and ENDR will be repeated a number of times just as if you done a copy/paste operation yourself</p> <pre>REPT 4 add a,c ENDR</pre> <p>This will assemble <code>add a,c</code> four times.</p> <p>You can also use REPT to generate tables on the fly:</p> <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> <p>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.<p> <h1>See also:</h1> <ul> <li><a href="macro.htm#labelsuffix">\@</a> </ul> <hr> <p>Last updated 21 June 1997 by <a href="mailto:[email protected]">Carsten Sorensen</a></p> </body> </html>
