Is there a way to check if a variable within a structure is available?
Example:
There is a structure handle containing different variables.
e.g:
handles.status // contain Status info of different pushbuttons --> in
fact status is a structure itself: handles.Status.pb1; handles.Status.pb2;
handles.I_ORG // contains original Image --> array
handles.I_RES // contains resulting Image --> array
Now I want to check if handles.I_RES existst
exists('handles.I_RES' , 'a') will return "0" even if handles.I_RES does
exist
isdef ('handles.I_RES' , 'a') will return "F" even if handles.I_RES
does exist
Thank you,
Philipp
