This is the same in VFP.

For example, if you call a UDF with something like this:

In the calling method:

myVal=4
z=MyUDF(myVal,this)

In MyUDF:

LParameters TheVal, TheObject

* the first param is a value
* the following line do not change the value in the calling prog
TheVal=5

* the second param is an ref to an object
* the folowing line affect the object in the calling prog
TheObject.left=50

HTH :-)
