- User Defined Variables
-
- User defined data files are ASCII text files that are created by the
- user with a text editor (see the READ File Format section in Appendix B
- in the manual). These files can only be accessed by the READ function;
- e.g.
-
- FILE = "jogtime"; Jogcal = 200 * READ/60;<*br>
- PLOT (Foodcal - Jogcal );
-
- Here 'jogtime' would be a text file containing the date and the number
- of minutes spent jogging during that day. 'Jogcal' then becomes a DAN
- variable that contains the number of calories expended jogging on the
- given dates and is usable in subsequent expressions.
