*
*        6/15/95 -*kob* added ifdef for STDERR_UNIT_SEVEN because stderr on

*                    precision of E and F labeling. The values are equivalenced to 
*                    ax_dec_pt(MODE_6D_LAB still turns on and off the listing of all 
*                    6 dimensions on SHOW commands.)
* V698  4/16 *acm* For ticket 2399: Apply MODE CALENDAR settings to F axes too
