INQUIRE LIST OF PARAMETRIC SURFACE INDICES
-
CALL SEQUENCE
CALL PQEPSI (WKID, N, ERRIND, OL, PSI)
INPUT PARAMETERS
- INTEGER WKID
- Workstation identifier
- INTEGER N
- List element requested
OUTPUT PARAMETERS
- INTEGER ERRIND
- Error indicator
- INTEGER OL
- Number of parametric surface table entries
- INTEGER PSI
- Nth element of list of defined parametric surface indices
PHIGS STATE
(PHOP, WSOP,*,*)
EFFECT
Returns the number of elements as well as the Nth element in the list of
parametric surface indices defined in workstation WKID's workstation
state list. If the inquired information is available, the error indicator is
returned as 0 and values are returned in the output parameters.
If the inquired information is not available, the values returned in the output
parameters are implementation dependent and the error indicator is set to one
of the following error numbers to indicate the reason for non-availability:
ERRORS
- 3
Ignoring function, function requires state (PHOP, WSOP,*,*)
- 54
- Ignoring function, the specified workstation is not open
- 59
- Ignoring function, the specified workstation does not have output
capability (i.e. the workstation category is neither OUTPUT, OUTIN, nor
MO)
