Hi:
I work in a UltraSparc with IDL 5.0, operating system SunOS 5.5.1
I brougth teh test1.sav file, and I was able to restore it. What I get
if I type "HELP" is the next:
---------------------------------------------------------
CATALOG STRUCT = -> HST Array[54]
CATALOG_NAME STRING = 'C5Vaug'
ID STRING = '5836C5Vaug'
LABEL STRING = 'Saturn C5Vaug'
N_IMAGES_CATALOG
INT = 54
PID STRING = '5836'
---------------------------------------------------------
I supose that that is all that was in that file !!!
Cheers,
I~nigo.
