Hi Nikola,
you can get a list of the contents of a save file before or without
restoring it by the IDL_Savefile object:
obj=obj_new('IDL_Savefile',filename)
contents=obj->Contents()
if contents.n_var ge 1 then print,'Variables: ',obj->Names()
if contents.n_sysvar ge 1 then $
print,'System Variables: ',obj->Names(/system_variable)
; and so on
;
obj_destroy,obj
Cheers, Heinz
