stepun(3G)

NAME
     stepun - specifies that a graphics window change size in discrete steps

FORTRAN 77 SPECIFICATION
     subroutine stepun(xunit, yunit)
     integer*4 xunit, yunit

PARAMETERS
     xunit   expects the amount of change per unit in the x direction.  The
             amount is measured in pixels.

     yunit   expects the amount of change per unit in the y direction.  The
             amount is measured in pixels.

DESCRIPTION
     stepun specifies the size of the change in a graphics window in discrete
     steps of xunit and yunit. Call stepun at the beginning of a graphics
     program; it takes effect when you call winope.  stepunit resizes graphics
     windows in units of a standard size (in pixels).  If winope is not
     called, stepun is ignored.
