When naming variables, use the following recommended format.

[Scope]TypeVariableName

Parameters

[ Scope]

Specifies a character that indicates the range of reference for the variable.

The following table lists suggested values for Scope.

Scope	Description
l	Local
t	Parameter
g	Public (Global)
p	Private (Default)

Note
In some cases, explicit scoping does not apply. For example, in the main program of a standalone application, there is no difference in visibility for variables scoped as PUBLIC or PRIVATE. In sample programs, the type prefix is always relevant and required.

Type

Specifies a character that indicates the data type of the variable.

The following table lists suggested values for Type.

Type	Description
a	Array
c	Character, Varchar, Varchar (Binary)
y	Currency
d	Date
t	DateTime
b	Double
f	Float
l	Logical
n	Numeric
o	Object
q	Varbinary, Blob
u	Unknown

VariableName

Specifies the name of the variable.
