LCase Function
Returns a string that has been converted to lowercase.
LCase(string)
Remarks
The string argument is any valid string expression. If string contains Null, Null is returned.
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".
