Name: GDSD_Rxxx Purpose: Read FITS data field File:
gdsd_wfits.shl Category: GDS Author: J.P. Terlouw Use: CALL
GDSD_Rxxx ( file_id, name, level, value, *error ) xxx can be
REAL, DBLE, INT, LOG or CHAR, depending upon type of `value'.
file_id = file identifier, CHARACTER name = name of FITS item.
CHARACTER*8 level = coordinate word specifying the substructure
from which the FITS item is to be obtained. If it is not present
at this level, higher levels are inspected until the item is
found or proven to be not present. INTEGER value = variable
receiving the data from the FITS record. Depending on `xxx', the
type can be REAL, DOUBLE, INTEGER, LOGICAL or CHARACTER*(*). If
a number was requested in a different format than has been
stored in the file, it is converted to the requested type
(integers are rounded) and an error code is returned. * error =
error return code, INTEGER -21 : number conversion error -22 :
incompatible type or level where item was found if call was
succesful. Updates: 25-May-87 original docu
