*  Mnemonic: FMceject
*  Abstract: This rotine ejects the current column such that the next tokin
*            is placed at the top of the next column on the page. If the
*            current column is the last defined column then pflush is
*            called to flush the page and then the first column is selected.
*            FMflush MUST be called prior to this routine... This routine
*            cannot call FMflush as it is called by FMflush and a loop might
*            occur.
*  Parms:    force - forces hard eject if true
*  Date:     6 May 1992
*  Returns:  Nothing.
*  Author:   E. Scott Daniels

*  Modified: 13 Jul 1994 - To convert t rfm
*             8 Dec 1994 - To write par mark at top only if not in def list.
