INQUIRE LIST OF REFLECTANCE INDICES
-
CALL SEQUENCE
CALL PQERFI (WKID, N, ERRIND, OL, RFI)
INPUT PARAMETERS
- INTEGER WKID
- Workstation identifier
- INTEGER N
- List element requested
OUTPUT PARAMETERS
- INTEGER ERRIND
- Error indicator
- INTEGER OL
- Number of data mapping bundle table entries
- INTEGER RFI
- Nth element of list of defined data mapping indices
PHIGS STATE
(PHOP, WSOP,*,*)
EFFECT
Returns the number of elements as well as the Nth element in the list of
reflectance 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:
See SET DATA MAPPING METHOD for a description of the data mapping method data
records.
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)
