 #!F-adobe-times-bold-r-normal--18*   inquiry #!EF #!EF #!I50 #!N specifies the query (see  #!Linquiry,dxall877 s Notes  #!EL  
). Some queries require an additional parameter (see value). #!N #!I0 
#!N  #!F-adobe-times-bold-r-normal--18*    #!F-adobe-times-bold-r-normal--18*   value #!EF #!EF #!I50 #!N specifies an item 
of information needed for identifying the appropriate subject of the query. 
For example, the "attribute" inquiry requires the name of the attribute.

#!N 1.  #!Ltab116,dxall877 t Table 16  #!EL  through  #!Ltab419,dxall877 t Table 19  #!EL  list the "inquiries" that can be 
made, the type(s) of object appropriate to each, an explanatory version 
of each, and the answer or type of answer returned. #!N 
#!I30 #!N 2. Inquiries that start with "is" are true/false queries, 
returning 1 (one) for "yes" and 0 (zero) for "no." Such 
queries can be reversed, however, by inserting "not" after the initial 
"is": An "is not" query also returns 1 (one) for "yes" 
and 0 (zero) for "no." For example, if the subject of 
the inquiry is a scalar field, "is scalar" returns 1 (one) 
and "is not scalar" returns 0 (zero). #!N #!I30 #!N 3. 
Any "is" query about a group whose members contain different types 
of objects will return 0 (zero) unless all members have the 
characteristic specified in the query. For example, if a group is 
composed of two fields, one scalar and one vector, the answer 
to the question "is scalar" will be 0 (zero). #!N #!I30 
#!N 4. Any inquiry that returns a scalar integer value can 
be made to return a value that is "1" higher or 
lower than that value. For example, "is array + 1" will 
return 2 (instead of 1) or 1 (instead of 0). #!N 
#!I30 #!N 5. Capitalization of an inquiry is optional and its 
words may be separated or run together. #!I0 #!N #!N  #!Rtab116
