the Visible Variable

There is one limit to fields to be aware of (admittedly this is seldom 
a problem):
 Fields can only have 65536 characters per line.
 Apparently Custom Properties do not have this limit.

 Yes, I do this all the time. There is no need to "go to" or to "show"
 the data stack, so the speed difference between using fields & using
 custom properties effectively disappears. However it makes debugging
 very easy as you can inspect & edit your data directly if needed.
 Backing up the data is also made simple, since you just save a copy of
 the stack.

 I make sure that each data field, check box,menu button or radio
 button has it's own unique name, then I collate all these names & the
 name of their card into a custom property of the data stack. I have
 generalised setData, getData handlers & functions that look at this
 list, find the appropriate data object on it's card, and either change
 or return it's value.

 This is working really well for me in several big projects.

 HTH,
 Sarah
