Generating keyword parameters from strings [message #67458]

Hi,

Does anyone know of a method of taking a string and turning it into a
keyword parameter? As an example, say I want to write a function:

function GetProperty, object, propertyName
object->GetProperty, 'propertyName'=value ; This is pseudocode --
this line is what I need
return, value
end

Obviously I can write this using execute, but I'd prefer to avoid that
if at all possible.
Also, although I use the GetProperty method as an example, this is a
more generic question about generating keyword parameter calls (so,
for example, David's nice discussion of a general GetProperty method
http://www.dfanning.com/tips/getproperty.html doesn't help here).

If I were just setting a value this would be easy to do with _EXTRA by
making my own structure. But for getting values it doesn't seem like
there is an easy equivalent (it would be nice to just make a
_REF_EXTRA structure if it behaved equivalent to _EXTRA but it seems
it doesn't).

Thanks,
Eric
