Hi all,

This should be fairly "basic" but have never figured it out...I know how to pass a variable or array to a function by reference (by prefacing with @) but in this case I want to pass an object to a method and force it to pass by "value" i.e. make a copy

loSomeObject=CREATE("empty")
ADDPROPERTY(loSomeObject,"FileName","C:\temp\test.doc")

loFileWhizBang.OutputFile(loSomeObject)

*** and method Outputfile ***

LPARAMETERS toFileObject

* strip the path off for some use
toFileObject.FileName = JUSTFNAME(toFileObject.FileName)

I *usually* load everything into local vars when doing things like this but trying to "tighten up" some code, I decided to do the alteration on the object property not realizing that it was not a LOCAL copy. So I instead tried to pass the object in a way that forces toFileObject to a local value. Could not figure and help files did not help.

Any way to do it?
