Re: Private variables question

Hi,

This is more from a mater of interest than any technical reason, but
there seems to be a lot of code around where the private variables
are called FSomething e.g.

TYPE TSomeType=class(object)
PRIVATE
FLocalVar : INTEGER;
PUBLIC
PROPERTY LocalVar : INTEGER READ FLocalVar;
END;

What I guess i'm asking is why prefix it with 'F'

F stands for Field, which is Pascal/Delphi parlance for a data member
of a class or record. The T in TSomeType stands for Type.

I guess F was originally used to distinguish the backing data member
from the property. I.e. a property with the name Status would often
have a backing data member with the name FStatus. I also guess that
this was convenient to recognize private members, so later on, the
principle of naming private fields starting with an F was used for all
private fields.
