#!F-adobe-helvetica-medium-r-normal--18* #!N #!CDarkGreen #!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 x 6 #!N format = text #!N interleaving = record #!N majority = row #!N field = Temperature #!N structure = scalar #!N type = float #!N dependency = positions #!N positions = regular, regular, regular, 1, .5, 3, 1.0, 2.0, .75 #!N #!N 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 #!F-adobe-times-medium-i-normal--18* Next Topic #!EF #!N #!N #!Ldgrdinf,dxall120 h Example 5.
