A problem with clearing fields on marked cards

Custom properties are very simple and very powerful. They work just like 
any other property.

You just make them up. Write:

set the isLabel of field "yourField" to "true"     --isLabel is the new 
custom property

Then ask:

answer the isLabel of fld "yourField"

You will get "true".

You will set the isLabel of all your other fields to "false". You can do 
this in a script.

This property is separate from the ordinary properties of your fields. For 
example, you might want a locked field in your application for some reason, 
and that would then interfere with your ability to distinguish it from a 
label field.
