status.i4.v = sr_file_select_register_c(select_id.i4.r, label.i1a.r,

	This routine registers a Save/Restore file selection field type for
	use by future calls to select_field_init_c.  Selection fields have
	the format "Label-<Entry>+".

	select_id	returned ID to be used in future calls to
	label		ASCII label to be placed to the left of the
			selection field
	label_length	number of characters in label (a value of zero
			will result in "label" being interpreted as a
			null terminated string)
	[category]	type of files to display
			(SR_GLOBAL -> global supersystem,
			 SR_LINAC -> Linac supersystem,
			 SR_BOOSTER -> Booster supersystem,
			 SR_MAININJECTOR -> Main Injector supersystem,
			 SR_SWITCHYARD -> Switchyard supersystem,
			 SR_TEVATRON -> Tevatron supersystem,
			 SR_MUON -> Muon supersystem,
			 SR_FRIG -> refrigerator supersystem,
			 SR_MISC -> miscellaneous supersystem,
			 SR_ARCHIVE -> archive supersystem,
			 SR_RECYCLER -> Recycler supersystem,
			 SR_SHOTS -> shots supersystem,
			 SR_CIRCULAR -> circular supersystem,
			 SR_MINIBOONE -> MiniBooNE supersystem,
			 SR_NUMI -> NuMI supersystem,
			 SR_PXIE -> PXIE supersystem,
			 SR_NML -> NML supersystem,
			 SR_MTA -> MTA (Muon Test Area) supersystem,
			 SR_SYCONFIG -> Switchyard configuration supersystem,
			 SR_CMTF -> CMTF supersystem,
			 SR_ALL_SYSTEMS -> all supersystems (default))
