AFIAK, VFP doesn't have a function to return the exact memory used by an object. The variable "o" only contains a pointer to a class. That class can be instanciated as a VCX (inside VFP) or as a COM (outside VFP).

As a rule of thumb, you use a variable locally for a method or procedure and use a class property for access in multiple class or module.

>I have come to learn that when I create an object using
>o=CREATEOBJECT('xxx.xx') and display memory, it shows 1 variable defined and 0 bytes used whereas when I actally declare a variable by o="string", it shows 1 variable defined and n bytes used. I do not know how the object exists without using any memory. Can anyone explain a bit about this? This atleast means to me that accessing object variables are better than using other declared variables.
