7.50 '.irpc SYMBOL,VALUES'...
=============================
Evaluate a sequence of statements assigning different values to SYMBOL.
The sequence of statements starts at the '.irpc' directive, and is
terminated by an '.endr' directive. For each character in VALUE, SYMBOL
is set to the character, and the sequence of statements is assembled.
If no VALUE is listed, the sequence of statements is assembled once,
with SYMBOL set to the null string. To refer to SYMBOL within the
sequence of statements, use \SYMBOL.
For example, assembling
.irpc param,123
move d\param,sp@-
.endr
is equivalent to assembling
move d1,sp@-
move d2,sp@-
move d3,sp@-
For some caveats with the spelling of SYMBOL, see also the discussion
at Macro.
