Hi Pete,
I'm not always good at staying on-topic, but maybe some of this will help...

I wrote myself a script to set the initial values of controls on a card in
preOpenCard. It looks for a custom property name cInitialValue, then
initialises the control to the value of the custom property, depending on
that type of control (field, button, etc).
I set the value of cInitialValue for checkboxes or radio buttons to either
true or false. My code then is:
set the hilite of control x of this card to (the cInitialValue of control x
of this card)
At run time, I get an error - value is not a boolean (true or false) near
"false"
Couple of things:
- since only buttons can have hilites, why not make your 'set' loop deal with
buttons only? e.g. "set the hilite of btn x of ...."
- an easy way to handle empty cprop hilite values (assuming empty = false) is:
set the hilite of btn x of this card to (the cInitialValue of btn x of this
card = true)
Doing this will prevent runtime hilite-setting errors (though your hilites may
still not be set to the correct values)
I'm suspecting this is because true and false are reserved words but the
set statement is treating them as literals (they are not in quotes in the
cprop though). However, the statement:
put (the cInitialValue of control x of this card) into control x of this
card
...works just fine when the value of the cprop is the word empty, also a
reserved word.
Right - buttons can contain text, so you can put empty or other text into them
without an error.
I'm reduced to what looks like a nonsenical if statement that checks the
cprop for true or false and sets the hilite of the button to true or false.
Looks really weird!
Wait until you get or set the text of an image! That always makes me squirm.
I've meddled enough for now...
