#!N  #!Rall118 Example 4. Naming a Field #!N #!EC #!N #!N 
By default, the Data Prompter names data fields in numerical order: 
field0, field1, and so on. But a data field can be 
named with a  #!F-adobe-times-bold-r-normal--18*   field #!EF keyword statement. #!N #!N Once 
the data are imported into Data Explorer, you can, for example, 
extract the name (using the Attribute module) and include it in 
a caption (using the Caption module). So if there are two 
types of data (e.g., temperature and pressure), each can be automatically 
and appropriately labeled with an identifying name, thereby "tagging" the associated 
data for future reference. As a result, it is also possible 
to import a field  #!F-adobe-times-medium-i-normal--18*   by name #!EF when there is 
more than one field. #!N #!N For this example suppose that 
the data in Example 1 are temperature values (see  #!Lex1a,dxall116 s To save the header file  #!EL  ). 
#!N #!I0 #!N  #!F-adobe-times-medium-r-normal--18*   #!N #!N #!I30 #!N 1. Open the 
record_scalar header file, as in Example 2. #!N #!I30 #!N 2. 
In the right-hand panel of the prompter, change  #!F-adobe-times-bold-r-normal--18*   Field name 
#!EF from "Field0" to "Temperature." To confirm this change, click on 
 #!F-adobe-times-bold-r-normal--18*   Modify #!EF at the bottom of the dialog box (note 
the instruction there). #!N #!I30 #!N 3. Repeat Example 1, Step 
10 (see  #!Lex1a,dxall116 s To save the header file  #!EL  ), to save the header file, which should 
look like: #!N #!I0 #!N #!EF #!N #!N #!N #!CForestGreen #!N 
 #!F-adobe-courier-bold-r-normal--18*   #!N file = /usr/lpp/dx/samples/data/record_scalar #!N grid = 5 x 8

majority = row #!N field = Temperature #!N structure = scalar 
#!N type = float #!N dependency = positions #!N positions =

end #!EF #!N #!N #!EC #!N #!N Note the change in 
the  #!F-adobe-times-bold-r-normal--18*   field #!EF keyword statement (line 6). #!N #!N #!N
