Denoting a Variable's Scope

In addition to prefixing a variable to denote its data type, you can and should use a prefix to denote its scope. The scope designation character precedes the data type prefix and is separated from it by an underscore. For example, to denote a module-level string variable, you can use a statement such as the following:

Dim m_strName As String 

Table 3-2 contains the prefixes that you use to describe scope.

 

Table 3-2. Prefixes for Variable Scope 

Prefix	Description	Example
g	Global	g_strSavePath
m	Local to module or form	m_blnDataChanged
st	Static	st_blnInHere
(no prefix)	Nonstatic, local to procedure	intIndex
