All VARA objects have a Script Access section on their definition pages that determines the error handling when scripts read the VARA object. You decide here what happens if scripts access the VARA object and the key to which they refer is not available.
The following options are available:
The script ends abnormally and a runtime error message is displayed in the Messages
Return initial values (Default)
The script continues executing although the key is not available. No runtime error is displayed. The report contains an empty string indicating that no key has been found.
Tip: Ensure that the keys of VARA objects always return a value if you want to use this option.
