There's no need to make these PUBLIC; the scoping applies to the VFP process, not to an OLE Object. I'd keep them local, to avoid side effects.

The problem is here - you're passing by value, rather than by reference. Try:

rslt = gnZip.Compress(@gcBigBlob, gcBigBlob, .t.)

this will get any result passed back into the original variable; otherwise, a copy of the data is passed and thrown away on return.
