### 7.56 `.irp` symbol`,`values...

Evaluate a sequence of statements assigning different values to symbol. The sequence of statements starts at the `.irp` directive, and is terminated by an `.endr` directive. For each value, symbol is set to value, 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

                 .irp    param,1,2,3
                 move    d\param,sp@-
                 .endr

is equivalent to assembling

                 move    d1,sp@-
                 move    d2,sp@-
                 move    d3,sp@-
