You can use the (somewhat arcane) list and execute forms of the macros. Be aware that they are different from the list and execute forms of other macros in that the list form generates executable code to populate the list in a "remote" (i.e. getmained) area, rather than simply mapping the expected parameters. The language is rather impenetrable, but becomes clearer when you code an example: "If you code MF=(L,address,label), the parameter list is built in the remote area specified. The expansion of the macro equates label with the length of the parameter list."
