'send' and behaviors

Hi Graham,

If you are using the same script for multiple cards, then you could use a property:

set the someProp of cd x to y

setProp someProp theData
  put the long id of the target into myTarget
  put line 1 of theData into field x1 of myTarget
  put line 2 of theData into field x2 of myTarget
  -- etc
end setProp

Maybe you don't even need theData and you could also use a simple command handler with the long id of a card as parameter.

If you really want to open a card before putting text into itse fields, you can do this:

lock messages
lock screen
push cd
put bla into fld x
pop cd
unlock screen
unlock messages

Best regards,

I'm afraid I didn't explain myself clearly, and I chose a stupid example of what I thought was the 'wrong' card reference, which obscured my real problem, which is this - the handler which I've called "doSomething" was written to take advantage of the context of the card it belongs on, so there are lots of references to objects like

What I was trying to do was to recreate the context from outside the card, so that this type of coding would still work. I naively assumed that if the defaultStack is changed by the 'send', then the defaultCard (OK I know there is no such language reference in LC but you know what I mean) would be changed too. In fact what happens is that the new current card is simply the last card to be 'shown' in the new stack. Really I don't even want to change stacks, just cards. My simplification also obscured the fact that what I really do from card "A" is to
