OL_WinCBCopy()
 Get text from the MS Windows clipboard.
──────────────────────────────────────────────────────────────────────────────

 Syntax

       OL_WinCBCopy() --> cText

 Arguments

      None.

 Returns

      The text contents of the Windows clipboard if there is any text
      there, or an empty string if there was an error or there was no
      text in the clipboard.

 Description

      OL_WinCBCopy() can be used to retrieve text from the Windows
      clipboard when your application is running in a DOS window.

      If for any reason the function is unable to locate any text in
      the clipboard the function will return an empty string. For the
      function to fail to copy from the clipboard one of the following has
      to happen:

              a) The application is not running under MS Windows.
              b) The DOS paste service is not available.
              c) The clipboard could not be opened.

      This function has been tested under under WFWG 3.11 and Windows 95.

      NOTE: Because this function needs to do some extra stuff when your
      application is running in protected mode I've had to make use of
      the CPMI library. You must link this in if you intend to use
      this function, even if you are linking for real mode operation.

 Examples

      // Attempt to grab some text from the clipboard and display it.

      If OL_IsWin()
         ? "The content is '" + OL_WinCBCopy() + "'"
      Else
         ? "You are not running under Windows"
      EndIf
