SYSTEM VARIABLE

Hi all,

I had just came out of this, and I don't know if it has anything related to how OOP in VFP work on no (system variable has some protection). But in my opinion. It has.

? _pageno && Return 1

LOCAL _pageno && Error: Must be variable or array

? m._pageno && error: variable '_pageno' is not found

CREATE CURSOR mycur (_pageno n(1)) && Error: Syntax Error

#1 why Local _systemvariable gives error? I cannot change it scope means it is protected? if yes who protect it or prevent it from changing?

#2 Why I cannot use m. before system variable?

#3 can I create a variable to work as system variable?
I mean gives error when I try to create field in table/cursor with the same name of system variable and gives error when i try to change it is scope.

#4 Error "Must be variable or array" and "variavle xxx is not found" means that _pageno is not variable? what it is?

TIA
