[ Type code = m ] The INFLD.DEF option is described more fully in its own topic, but briefly, it allows a method of automatically adding a series of type codes to every INFLD call. m will disable this ability, and even disable the search for the INFLD.DEF module, which may shave a few CPU ticks off each call.
Note that INFLD.DEF is replaced by SBR=INFDEF: in miame.ini, but the m code still serves the same purpose..
