Yes, Dave's suggestion works in context - but my problem that the
context of the handler is different from that of the field whose id I
want to pass as a parameter: this has to be true if the handler is to
be at all worthwhile, as it does its work on ids of objects from
various stacks etc. That's where the difficulty lies. Geoff Canyon's
idea of making sure the RR engine can't parse the id reference seems
to be the way to go:
I've hit this before. I generally postfix a cr like so:
put (the long id of fld "myField" of cd "myCard" of stack
"myStack") & cr into tParam
myHandler tParam
Then in myHandler:
on myHandler pID
delete char -1 of pID -- ready to go now
or if it could be a list:
on myHandler pIDList
repeat for each line tID in pIDList
Although somehow I would expect there to be a way of passing a 'parse-
able' string **as** a string, but apparently not.
Thanks to both of you.

Hi,
Instead of doing:
myHandler (the long id of fld "myField" of cd "myCard" of stack
"myStack")
do
myHandler (the long id of me)
That should fix it!
All the Best

I've never come across this before, and it's got me confused. I
have a handler, say "myHandler" that has a couple of parameters
which are intended to be the long ids of objects (actually fields).
The handler manipulates the fields, something like
on myHandler para1
do "put empty into"&¶1
...
end myHandler
I find that this works if the parameters are set in the same
context as the handler itself - for example in a 'mouseUp' handler
on the card where I've put the code of myHandler, but if I call it
from elsewhere with a call like
myHandler (the long id of fld "myField" of cd "myCard" of stack
"myStack")
I find that during the call the engine evaluates the parameter and
passes me the contents of the field, and not the reference to the
field. What I want is to pass the long id to my handler as a
**string**. I can't see why this doesn't work, and more importantly
so far I'm stuck for a way round it. I've tried
put the long id of fld "myField" of cd "myCard" of stack
"myStack" into temp
myHandler temp
but it has exactly the same effect.
What am I doing wrong?
