Generate-form keyword

The format of the MF keyword for the generate form is:

MF=(G,address[,label])

where:

G: Specifies that this is the generate form of the macro.
address: Specifies the address of a remote area in which the parameter list is to be built. The area must begin on a fullword boundary.
label: Specifies a unique name that is used in an EQU instruction in the expansion of the macro. Label is equated to the length of the parameter list. You do not have to know the length of the parameter list if you code label; the expansion of the macro determines the amount of storage required.

If you code MF=(G,address), the parameter list is built in the remote area specified.

If you code MF=(G,address,label), the parameter list is built in the remote area specified. The expansion of the macro equates the length of the parameter list to label.
