Welcome to the World of Naming Conventions.
There are those who sneer at prefixes of /any/ kind on variable
names, because they know (or, rather, their mega-expensive
IDE tells them) what DataType a variable is and whether it's
Private, Public, Global or whatever.
Those of us in the Real World, who still have to fight the Good
Fight [occasionally] with the likes of Notepad prefer to be able
to read this kind of thing for ourselves.
At the /very/ least, include a "Scope" prefix on your variable names,
as in
iCount ' [local] Integer variable
smCount ' String Variable [at *M*odule (or class) level]
lgCount ' Long variable [*G*lobal]
That way, you /can't/ get your variables mixed up.
HTH,
Phill W.
