They are always expanded immediately after their definition.During expansion, their macro body is repeated n times (0 <= n <= 65535).Repeat macros start with the keyword REPT, followed by an expression, whichmust be known on <NOBR>pass 1</NOBR>. In analogy to callable macros, there is a macrobody, which must be terminated with an ENDM instruction:</P><P><BLOCKQUOTE><STRONG><PRE>REPT <expression><body line 1><body line 2> . .<body line m>ENDM</PRE></STRONG></BLOCKQUOTE></P><P>The expression value specifies how many times the macro body is to berepeated.
