} From my notes (ultimate source is the VMS fiche, of course):
} EXE$EPID_TO_PCB		extended PID (user visible) to PCB address
} EXE$IPID_TO_PCB		internal PID to PCB address
} EXE$EPID_TO_IPID	extended PID to internal PID
} EXE$IPID_TO_EPID	internal PID to external PID
} 
} Calling sequence is:
} 
} 	MOVL	<input pid>,R0
} 	JSB	G^EXE$...
} 	BEQL	<error-condition>
} 
} Output PID or PCB address is returned in R0.  R0 is set to 0 on an error.
} The condition codes are set according to the R0 value, hence the suggested
} BEQL after the JSB for error handling.
 
One further note: the address conversion routines (EXE$%PID_TO_PCB) require
they be all in kernal mode with IPL >= IPL$_SYNCH. This is according to the
official documentation for these routines (yes, it exists!).

These routines were documented in the _VAX/VMS_Release_Notes_Version_4.0_,
order number AA-Z105A-TE, section 8.5.5. No, this was not put in the release
notes for any other version of VMS.
