For me, it worked every time but I've realised that there is a flaw in
my concept; it assumes that the StrongED$Tmp_ keep pointing at the same
mode. Easily done during experimentation but not really practical during
actual use. So, I took a bit of time to come up with a better way.

Below is a description of what I ended up with. To keep things separate
I used a new mode (TestReparse) but the idea can be applied to any mode.


  First make sure that the ModeFiles that need to be swapped are in
  StrED_cfg.UserPrefs.Modes.<mode> and that the alternative ModeFile
  is named ModeFileA. In there also create a directory called: 'Tools'.


  Create an Obey file named SwapMF1 and save it in the Tools directory
  (NB the LoadOne function should be on the same line as Message).

    |*** Start of SwapMF1

    Set SwapMF$Dir <StrongED$Tmp_WriteDir>Modes.<StrongED$Tmp_ModeName>

    Rename <SwapMF$Dir>.ModeFile  <SwapMF$Dir>.ModeFileB
    Rename <SwapMF$Dir>.ModeFileA <SwapMF$Dir>.ModeFile
    Rename <SwapMF$Dir>.ModeFileB <SwapMF$Dir>.ModeFileA

    Message StrongED_ExecCmds SetTmp()
      LoadOne("<StrongED$Tmp_ModePath>.ModeFile")
    Filer_Run <StrongED$Tmp_ModePath>.Tools.SwapMF2
    Unset SwapMF$Dir

    |*** End of SwapMF1


  Create a second Obey file, SwapMF2, also in Tools that contains this:

    |*** Start of SwapMF2

    Message StrongED_ExecCmds SaveKill()

    |*** End of SwapMF2


  Add a toolbar icon that runs the SwapMF1 to both ModeFiles:

    Functions
      Icon     sm!edit
      Select   SetTmp() Run("Filer_Run <StrongED$Tmp_ModePath>.Tools.SwapMF1")
    End


  Clicking on the new toolbar icon should swap the ModeFiles and reparse
  the one now called ModeFile.


  To test if it worked I added a simple keyList to ModeFile:

    KeyList
      c-Q    InsertStr("ModeFile")
    End

  The same for ModeFileA except that it inserts "ModeFileA".

  After each click on the icon the inserted string changed, from
  'ModeFile' to 'ModeFileA' then back to 'ModeFile' etc.


This is a much better way than my original scheme, sets StrongED$Tmp_
variables correctly and no need for another task to launch SwapMF1.

Please give it a try and let me know if it works.

Cheers,
Fred.
