Syntax

LCase(string)

The string argument is any valid string expression. If string contains Null, Null is returned.

Remarks
Only uppercase letters are converted to lowercase; all lowercase letters and non-letter characters remain unchanged.

The following example uses the LCase function to convert uppercase letters to lowercase:

Dim MyString
Dim LCaseString
MyString = "VBSCript"
LCaseString = LCase(MyString) ' LCaseString contains "vbscript".
