************************************************************ |
| 6 |
This program allows you to produce B and L profiles in |
| 7 |
latitude, longitude, year or altitude. |
| 8 |
In each of the following windows you will be asked to enter |
| 9 |
one or more values, defining the conditions for your tables. |
| 10 |
In each window the current value(s) is (are) shown in the right |
| 11 |
upper corner (#...#). You can choose the current values by |
| 12 |
entering / at the prompt. |
| 13 |
If you enter a wrong character or a value outside the allowed |
| 14 |
parameter range, the program will ask you for a new entry. |
| 15 |
After your tables are displayed, you can change any parameter |
| 16 |
you wish to change and create a new profile. |
| 17 |
You can leave the program at any point by entering Ctrl Z. |
