V_CLSWK()

id: iexp

The numbers 1 and 2 are default values for the settings of the VDI parameters.
They can be changed (see WORK_OUT()).

The function V_OPNWK() (Open Workstation) returns the handle 'hd' for the
specified device 'id'. In addition, further information about the device may be
requested by means of INTOUT() and PTSOUT() (see VDISYS in the section 'System
Routines').

The optional 10 parameters are as follows:
   1   Default line type      vsl_type()
   2   Default line color     vsl_color()
   3   Default marker type    vsm_type()
   4   Default marker color   vsm_color()
   5   Default font           vst_font()
   6   Default text color     vst_color()
   7   Default fill interior  vsf_interior()
   8   Default fill style     vsf_style()
   9   Default fill color     vsf_color()
  10   Coordinate type flag   0 = NDC (Normalized Device Coordinates)
                              2 = RC (Raster Coordinates)

If the parameters are left out, the values '1,1,1,1,1,1,1,1,1,2' are used.

The function V_CLSWK() (Close Workstation) closes the current workstation
opened with V_OPNWK() and flushes its buffers. In addition a V~H=-1 is carried
out.

Example: See V_CLRWK().

Memo: V_OPNWK() with the extra parameters does not work correctly in the
      editor or compiled.

      V_CLSWK() seems to return INTOUT(0), but it's useless. This VDI call is
      documented as not having a return value.
