The only thing I know of is an array. Not sure if this has to be retained between sessions. If so, then I would suggest using a server instance to hold the array. You can use a custom property on _VFP that is added with ADDPROPERTY(_VFP, "CustomProperty", CREATEOBJECT("Empty")). You can then add needed properties to _VFP.CustomProperty such as the list of objects and a Count property.
