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.
