Example

' This example uses the LTrim and RTrim functions to strip leading and 
' trailing spaces, respectively, from a string variable.  It uses the 
' Trim function alone to strip both types of spaces.
' LCase and UCase are also shown in this example as well as the use
' of nested function calls
 
Sub Main
   MyString = "  <-Trim->  "   ' Initialize string.
   TrimString = LTrim(MyString)   ' TrimString = "<-Trim->  ".
   MsgBox "|" & TrimString & "|"
   TrimString = LCase(RTrim(MyString))   ' TrimString = "  <-trim->".
   MsgBox "|" & TrimString & "|"
   TrimString = LTrim(RTrim(MyString))   ' TrimString = "<-Trim->".
   MsgBox "|" & TrimString & "|"
   ' Using the Trim function alone achieves the same result.
   TrimString = UCase(Trim(MyString))   ' TrimString = "<-TRIM->".
   MsgBox "|" & TrimString & "|"
End Sub
