  Parameters:
    1
      Execute application and capture output.
    "PROGRAM"
      File for execution. Can be "", if need to change "REPATTERN" and "RETAGS".
    "WORKDIR"

    "REPATTERN"
      Regular expression pattern. Applied to each output line to jump to the text from the panel.
    "RETAGS"
      Pattern matches map.
        /FILE=\1         file to jump.
        /GOTOLINE=\2:\3  line and column to jump.
        /GOTOBYTE=\2     byte offset to jump.
        /GOTOCHAR=\2     character offset to jump.
        /FRAME=\1        frame data handle to jump.
    INPUTCODEPAGE
      Codepage of the input text for executed file.
      If -1, codepage will be autodetected.
      If -2 or not specified, codepage from plugin settings will be used.
    OUTPUTCODEPAGE
      Codepage of the output text from executed file.
      If -1, codepage will be autodetected.

    FLAGS (sum of the following):
         1  Don't create output panel.
         2  Hide input line.
         4  Save all documents before execution.

        64  Create, but don't show output panel. Requires closing through Call("Log::Output", 6).
       128  Close output panel, if application exit code equal to zero.

      4096  Source input - selection or all document if selection is empty.
      8192  Source input - all document.
     16384  Source input - selection.

  Example (batch file execution for compilation):
    Call("Log::Output", 1, `"%d\Build.cmd" /S`, "%d", "^\s*(.*)[(:](\d+)([,:](\d+))?[):]", "/FILE=\1 /GOTOLINE=\2:\4", -2, -2, 4)

Call("Log::Output", 2, *WINDOW, *DOCK)
  Parameters:
    2
      Get text output window handle. Use with Scripts plugin.
    *WINDOW
      Pointer to a variable, that receives text output window handle.
    *DOCK

  Example:
    WScript.Echo(GetOutputWindow());

    function GetOutputWindow()
