    The colon is not used to separate statements in a line, as WimpBasic only
    allows one statement per line. The colon has two functions. The first one
    is to separate groups and variables. All global variables belong to a group
    and to use them you enter them as Group:Variable.
     
    Example: Group:Variable
     
    The second use for the colon is to define a label for the Goto or Restore
    statements. To do this, you must have a colon as the first character on the
    line and follow it with a valid label. Labels have the same rules as variable
    names except that the characters (, ), % and $ are not allowed.
     
    Example:
    On Error Goto LowMemory
    Rem Some code to handle low memory
    :LowMemory
