crg_tecar_c_to_ftn (ul_crg)

	status.i4.v = crg_tecar_c_to_ftn(file_number.i4.r, ramp_data.s.r)

	This routine reads the CRG TECAR ramp and places the data in
	the user preallocated structure "this_ramp".

	file_number	CRG file number to read  (If "file_number"
			is zero, this routine will automatically
			search for the active file.)
	ramp_data	returned CRG TECAR ramp data
			(structure of type CRG_RAMP_FTN)
			(The caller should allocate memory before calling
			 this routine.)

	This function returns ACNET status values as follows:

	FSHARE_OK		success
	FSHARE_xxx		error in reading file
	CBS_INVARG		file number out of range or null structure
				pointer passed
