# MX\_IXCALL > [HTML Version](mx_ixcall.htm) **xcall MIAMEX, MX\_IXCALL, sbrnam, xcbadr, status** MX\_IXCALL (MIAMEX 115) allows you to forward the calling parameter from one [SBX](sbx.htm.md) subroutine to another, evaluating the new subroutine name on the fly. **Parameters** _sbrnam_ ([String](string.htm.md)) \[in\] is the name of the new subroutine to call. _xcbadr_ (F6) \[in\] is the address of the parameter structure which was passed to the original routine. _status _(F6) \[out\] will return 0 for success, >0 for subroutine not found or unable to load, else <0 for other system errors. **Comments** MX\_IXCALL is used in the RXCALL.SBX routine, which allows you to remotely call a routine running on another machine. See the documentation on [SBX Subroutines](sbxsubroutines.htm.md) about RXCALL, as well as for information on the subroutine parameter structure.
