INIT:
   call notify('slider1','_set_min_',-2.20);
   call notify('slider1','_set_max_',2.20);
   call notify('slider1','_set_inc_',0.10);
   slider1 = 0;
return;

ZOOM:
      /* halve the current increment */
   call notify('slider1','_get_inc_',inc);
   call notify('slider1','_set_inc_',inc/2);
return;

UNZOOM:
      /* double the current increment */
   call notify('slider1','_get_inc_',inc);
   call notify('slider1','_set_inc_',inc*2);
return;

MAIN:
      /* The numeric text entry field named 
         SVALUE */
      /* shows the numeric value of the 
         slider.    */
   svalue = slider1;
return;
