#!CDarkGreen #!N  #!Rall115 Example 1. Scalar Data on a 
Regular Grid #!N #!EC #!N #!N This example illustrates how a 
simple floating-point scalar field, on a regular grid, might be imported 
from a text file named "record_scalar." The origin of the grid 
is [1 3 2], with deltas of 0.5, 1, and 0.75 
in the x, y, and z directions respectively. #!N #!I0 #!N 
 #!F-adobe-times-medium-r-normal--18*   #!N #!N #!I30 #!N 1. In the Data Prompter initial 
dialog box, choose Grid or Scattered File; then select the leftmost 
button in the row labeled  #!F-adobe-times-bold-r-normal--18*   Grid type #!EF (regular grid). 
#!N #!I30 #!N 2. Confirm that  #!F-adobe-times-bold-r-normal--18*   Number of variables #!EF 
is set to "1" and that the  #!F-adobe-times-bold-r-normal--18*   Single time step 
#!EF toggle button is activated. #!N #!I30 #!N 3. For  #!F-adobe-times-bold-r-normal--18*   
Data organization #!EF , confirm that the  #!F-adobe-times-bold-r-normal--18*   Block #!EF (i.e., 
record) toggle button is activated. #!N #!I30 #!N 4. Click on 
 #!F-adobe-times-bold-r-normal--18*   Describe Data #!EF to bring up the "simplified" prompter. #!N 
#!I30 #!N 5. Enter the path name of the data file 
in the  #!F-adobe-times-bold-r-normal--18*   Data file #!EF field: #!CForestGreen #!N #!N  #!F-adobe-courier-bold-r-normal--18*   
#!N /usr/lpp/dx/samples/data/record_scalar #!EF #!N #!N #!EC #!N #!I30 #!N 6. Browse 
the data file if you like by choosing  #!F-adobe-times-bold-r-normal--18*   Browser #!EF 
from the ellipses to the right of the  #!F-adobe-times-bold-r-normal--18*   Data Field 
#!EF field. #!N #!I30 #!N 7. Enter the values "5," "8," 
and "6," in that order, in the first three  #!F-adobe-times-bold-r-normal--18*   Grid 
size #!EF fields. The number of data values is 240 (i.e., 
5 * 8 * 6). #!N #!I30 #!N 8. Confirm that 
 #!F-adobe-times-bold-r-normal--18*   Data format #!EF is set to ASCII (text). #!N #!I30 
#!N 9. Confirm that  #!F-adobe-times-bold-r-normal--18*   Data order #!EF is set to 
Row. #!N #!I30 #!N 10. Finally, set the first three origin-delta 
pairs (in the  #!F-adobe-times-bold-r-normal--18*   Grid positions #!EF section of the prompter) 
to: 1.0, 0.5; 3.0, 1.0; and 2.0, 0.75, in that order. 
#!N #!N Since the data order is Row (i.e., last index 
varies fastest), the first six data values are associated with positions 
[1 3 2], [1 3 2.75], [1 3 3.5 ], [1 
3 4.25], [1 3 5], and [1 3 5.75 ]. (If 
the data are stored so that "last index varies slowest,"  #!F-adobe-times-bold-r-normal--18*   
Data order #!EF should be set to Column.) #!N #!I30 #!N

appears, position the cursor in the  #!F-adobe-times-bold-r-normal--18*   Selection #!EF field (at 
the point indicated by the carat). #!N #!I30 #!N c. Enter 
the name of the file (record_scalar). #!N #!I30 #!N d. Click
