PROGRAM 1: Element creation and inquiring

CHARACTERISTICS: nnnn

OPERATOR SCRIPT: passive test.

DESIGN:

Use <inquire current element content> throughout to determine:
    celval = current element value as set by program
    recval = auxiliary element values implied by the standard's
             representation conventions.

Use <inquire current element type and size> throughout to determine:
    celsiz = current element size

*** *** *** *** ***   Marker type   *** *** *** *** ***
mtval = 17
<set marker type>:
    marker type = mtval

TEST: #SR 1 4
      "<Inquire current element type and size> should return
       marker type as the type of the created element and the
       appropriate element size."
<inquire current element type and size> for current element type
pass/fail depending on
  (current_element_type = marker type and
   celsiz               = values specified by the standard)

TEST: #SR 2 4
      "<Inquire current element content> should return the standard
       representation for the marker type value."
<inquire current element content> for current element representation
pass/fail depending on
  (celval = mtval and
   recval = auxiliary values specified by the standard)

*** *** *** *** ***   Marker size scale factor   *** *** *** *** ***
<set marker size scale factor>:
    marker size_scale_factor = 0.25

TEST: #SR 1 13
      "<Inquire current element type and size> should return marker
       size scale factor as the type of the created element and the
       appropriate element size."
<inquire current element type and size> for current element type
pass/fail depending on
  (current_element_type = marker size_scale_factor
   celsiz               = values specified by the standard)

TEST: #SR 2 13
      "<Inquire current element content> should return the standard
       representation for the marker size scale factor value."
<inquire current element content> for current element representation
pass/fail depending on
  (celval = 0.25 and
   recval = auxiliary values specified by the standard)

*** *** *** *** ***   Polymarker colour index   *** *** *** *** ***
<set polymarker colour index>:
    polymarker_colour_index = 2

TEST: #SR 1 20
      "<Inquire current element type and size> should return
       polymarker colour index as the type of the created element
       and the appropriate element size."
<inquire current element type and size> for current element type
pass/fail depending on
  (current_element_type = polymarker_colour_index
   celsiz               = values specified by the standard)

TEST: #SR 2 20
      "<Inquire current element content> should return the standard
       representation for the polymarker colour index value."
<inquire current element content> for current element representation
pass/fail depending on
  (celval = 2 and
   recval = auxiliary values specified by the standard)
