flag, xmin, ymin, xmax, ymax: iexp

This instruction makes it possible to define a 'clipping' rectangle, to which
Line-A screen output will be limited. The coordinates of the top left and
bottom right corners of the Clipping rectangle are given by xmin, ymin, xmax,
and ymax. If 'flag' is given a non-zero value the clipping is active, otherwise
(if flag=0) it is switched off. ACLIP is not valid (unfortunately) for PSET,
PTST(), ALINE, HLINE, and BITBLT.

Memo: This is not really a Line-A function per say.
      It simply writes the parameters into the Line-A variables.

      ACLIP -> CLIP, XMINCL, YMINCL, XMAXCL, YMAXCL (Line-A variables)
