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.

Thanks in advance
