We could use the default screen (Screen 0) just the way it is. But let’s dress it up because this will be the screen used for maintaining our product inventory. Have your Quick Reference Guide handy.
1. From the main menu, select option “2 - Define Screens".
2. Select screen 0.
3. Go into update mode. Press <U>
4. First, let’s give this screen a reverse video heading. Move the cursor to position “3,1”.
5. Press <ALT> <F9>; the cursor row and column numbers should now be in reverse video.
6. Use the <SPACE BAR> to create a reverse video line (out to position “3,30”). Type: Inventory Maintenance and then press the <SPACE BAR> to move to position “3,80”.
7. Press the <SPACE BAR> once more to “wrap” the cursor to the beginning of the next line, position “4,1”
8. Turn off the reverse video mode by pressing <ALT> <F9> again. Check the cursor row and column indicator numbers to see that the reverse video is off.
9. We want to relocate this portion of the data-entry screen. We accomplish this very simply with a few keystrokes. With the cursor at “4,1” press <F7>. Move to “10,23” and press <M>. Move down two lines and press <Tab> twice. Now press <RETURN>.
10. At position “11,54” type: Profit %: !pr
11. At position “12,50” type: Total Profit: !tp The colons (:) in both headings should be aligned.
12. To put the final touch on our data-entry screen we want to draw a box around our input fields. Position the cursor at “5,14”.
13. Press <F7>. Position the cursor to “13,73” and press <D> (Draw Box).
14. Now return the cursor to the asterisk on line 10, position 35 and change the asterisk to an exclamation point. Do the same for the asterisk on line 12, position 35. The exclamation point is the “protected field” indicator. This will prevent data-entry into these fields (they will be calculated by the processing in the next lesson).
15. If your computer supports color, you may want to add colors to this screen. To do so, press <CTRL> <F10> for color help, press <RETURN> to come back to the screen, select the colors by using <ALT> and a function key, and <SHIFT> and a function key. Now position the cursor to where you want the color to start and press <F7>. Position the cursor to where you want the color to end and press <F>. Your screen format should look like the following:
Figure 14-1. “prod” File Screen 0
16. When the screen is complete, save it, by pressing <ESC>, and exit to the main menu by pressing <X>.
