'the owner' query

[dunbarx at aol.com]

Hi.


Just a thought. Put parentheses around all explicit object references and see if the script and msg work as advertised:




if (the owner of tgrcID) <> (grp "theProtectedGroup") then ...

Subject: 'the owner' query


I'm trying to use the concept of 'the owner' to detect certain grouped controls 
on a card, where as it happens I want to skip a looped operation on these 
particular objects. I'm using a construction like:

   if the owner of tgrcID <> grp "theProtectedGroup" then ...

In this example tgrcID contains a graphic's ID - in fact it's a line from 'the 
selectedObjects'. The group mentioned exists and is on the same card. When 
executed as part of an apparently error-free script, or in the message box in 
the form

   put the owner of tgrcID <> grp "theProtectedGroup"

I get this runtime error:

> Error description: Factor: error in right operand

Putting bits of the comparison in brackets, wrapping it up in 'do' etc don't 
make a difference to the error. Trying to use value(tgrcID) produces a different 
error.

If I put this in the message box when I have a specific ID in tgrcID

   put the owner of tgrcID

I get the expected answer, i.e. the type and name of the owner. So it looks as 
if there is a syntactical problem of some kind in the engine.

Knowing the above, I can do a workaround, by executing something like

   put the owner of tgrcID into temp
   put temp <> "grp" && quote & "theProtectedGroup" & quote

which doesn't give an error, just the expected result (true or false).

Is it me, or is it a bug?

TIA

Graham
