a more general digression on manipulating rev object by names and not  
by value:

as far as I am concerned, it seems to me that, for instance, if  
<name> is the long name of a filed, if you want to put empty into the  
field with name <name>, then you have to script
do "put empty into" && <name>
and then probably have to deal with the quotes in the long name (it  
seems I have had to do this countless times when executing a loop on  
object names in a group/card/whatever)

The OP was concerned to setting a variable value when knowing only  
its name, and Eric's answer was to use the "do" command. This is  
something I have used quite frequently in my HC days, but  
unfortunately use of the "do" command is severely restricted in  
standalones (with reasons I can understand).

I was hoping that the reference operator @ would do the trick, i.e.  
passing the name of the variable instead of the variable itself. The  
following button handler works:

---------------
on mouseUp
   put 1 into myVar
   doput "hello",myVar
   answer myVar
end mouseUp

on doput theText, at theVarName
   put theText into theVarName
end doput
------------------

the following causes an execution error when trying to execute the  
doput handler

----------
on mouseUp
   put 1 into myVar
   doput "hello","myVar"
   answer myVar
end mouseUp

on doput theText, at theVarName
   put theText into theVarName
end doput
----------

If something similar could be done without using the "do" command,  
for instance by passing arguments by name (i.e. a string), I would be  
very happy to hear about it.
