[Gambas-user] trimming extra spaces from within a string.

Just a question, why not just use SPLIT function to split all the text and next reassemble it by a JOIN

Public Sub TrimText(sText As String)

  Dim aText As String[]

  atext = Split(sText, " ", Chr(140), True)

  Print atext.Join(" ")


Too simple maybe
