Passing parameters by reference

[Pete]

Dick:

Thanks for the script, another little nugget of knowledge added to my LC
store!

I have entered an enhancement request - it's # 10070

Dar:

The function in question is a general purpose one that gets called from
many places.  Sometimes I need to pass an array element and other times
just a simple variable so I'd rather not complicate things by passing in an
extra parameter that holds the array key if it is an array that's being
passed.  But that is a possible solution so thanks for the suggestion.

Bob:

Creating a temporary array works, of course, and that's what I'm doing for
now.  But it defeats the whole purpose of passing the parameter by
reference since now I have to put the temporary array back into the real
array after the call.  I may as well just change the function to return the
result of its code and pass the parameter by value instead of reference.
