VarType(variable)
Description
VarType returns an integer that indicates the type of a variable. The required parameter, variable, is any variable that doesn't contain a user-defined type.
When variable is an array, the value returned is equal to the array constant plus the constant that specifies the element-type.

Rem VarType Example 'VarType returns variable type as an integer Dim nInteger, nSingle nInteger = CInt(44) Print 44 & " is VarType " & VarType(nInteger) nSingle = CSNG(99.44) Print 99.44 & "isVarType" & VarType(nSingle)
Output
