Syntax

WORD vst_rotation( handle, angle )
WORD handle, angle;

Function      vst_rotation() sets the angle at which graphic text is
              drawn.

Opcode        13

Availability  Supported by all drivers. For specific character rotation
              abilities, check the values returned in vq_extnd().

Parameters    handle specifies a valid workstation handle.
              angle specifies the angle at which to rotate text in
              tenths of degrees as follows:



Binding       contrl[0] = 13;
              contrl[1] = 0;
              contrl[3] = 1;
              contrl[6] = handle;

              intin[0] = angle;

              vdi();

              return intout[0];

Return Value  vst_rotation() returns the value of rotation actually set.

Comments      Bitmap fonts may only be rotated at 0, 90, and 270 degrees.
              Outline fonts may be rotated at any angle with FSM.
