De Tab Function
Co Decs Class

Public Function DeTab( _
      ByVal vValue As Variant _
    , Optional ByVal vTabWidth As Variant _
    ) As Variant

"Expand Tabs To Spaces"
Replaces tab characters (Chr$(9)) with the number of spaces required to advance the print position to the next tab stop.
Function assumes that there is a tab stop every vTabWidth characters.

Examples: 
    DeTab("12" + Chr$(9) + "345" + Chr$(9) + "6789") = "12      345     6789"
    DeTab("12" + Chr$(9) + "345" + Chr$(9) + "6789", 4) = "12  345 6789"
    DeTab("12 345 6789") = "12 345 6789"

    vbTab Property
vValue: String whose tab characters are to be replaced by an appropriate number of space characters. Function returns Null if vValue is Null or cannot be fixed up to a String.

vTabWidth: The number of positions between each tab stop. vTabWidth defaults to 8 (eight) if it is missing or Null or cannot be fixed up to a String. If vTabWidth is 8 (eight) for example, there will be a tab stop after columns 8, 16, 24, 32, etc.

vTabWidth is set to 1 (one) if it is less than 1 (one).

Note: This function properly handles string containing carriage return and line feed characters. It assumes that carriage return characters reset the print position to column 1 (one) and that line feed characters have no effect upon the current print position.
