PROGRAM 3: Error 152 handled by system

CHARACTERISTICS: ynny

OPERATOR SCRIPT:
See OPERATOR SCRIPT for Program 1.

DESIGN:
Throughout this program, every time an error is signalled (as noted
by the tag "signals error"), the system-defined error handler should
call <error logging> to write in error message on the error file.

Given invalid viewport limits to test if functions 88,89 generate error 152:
ignoring function, invalid viewport: XMIN>=XMAX, YMIN>=YMAX, or ZMIN>ZMAX.

*** *** ***  Generate errors; test absence of side effects  *** *** ***

<open workstation> wkid

Use <inquire display space size 3> to get:
     maximum display size dx,dy,dz (DC)
xx = dx/2
yy = dy/2
zz = dz/2
<set workstation viewport 3> with xmin=0.0, xmax=xx, ymin=0., ymax=yy,
     zmin=0., zmax=zz
<set workstation viewport 3> with xmin=xx, xmax=0., ymin=0., ymax=dy,
     zmin=0.,zmax=dz: signals error
Use <inquire workstation transformation 3> to get:
     current workstation viewport limits: xmin1,xmax1,ymin1,ymax1,zmin1,zmax1
TEST: #SR 3
      "If <set workstation viewport 3> signals an error because the specified
       workstation viewport limits are invalid: XMIN>=XMAX, YMIN>=YMAX, or
       ZMIN>ZMAX, it should not cause any other effect."
pass/fail depending on (system state = PHIGS-open and
                        workstation state = open  and
                        xmin1=0 and xmax1=xx and ymin=0 and ymax=yy and
                        zmin1=0 and zmax1=zz)

<set workstation viewport 3> with xmin=0., xmax=dx, ymin=yy, ymax=0.,
     zmin=0.,zmax=dy: signals error

<set workstation viewport 3> with xmin=0., xmax=dx, ymin=0., ymax=dy,
     zmin=zz,zmax=0.: signals error

<set workstation viewport 3> with xmin=0., xmax=dx, ymin=yy, ymax=yy,

<set workstatino viewport> with xmin=xx, xmax=0., ymin=yy, ymax=0.:
