The program remembers the last 8 functions typed in. You can recall the previous function with the up arrow. Alternatively, you can use the user function mechanism to define the function you wish to manipulate. Use Ctrl-F to define the function, and refer to it as f(expression). >Second, and more serious, if one >has used the program options extensively, the program crashes the PC >(memory allocation error) at exiting. I have fixed this in my development version. If you avoid using the help screen the program won't crash. (Since I don't use the help screen, it took me a while to notice this one.) There is another bug with plotting parametric that you didn't notice which I have also fixed. The development version also includes complex variables and will be released as soon as I can figure out how to evaluate the bessel functions and gamma function for complex arguments. -- Adrian Mariano, author of plot61 theorem@blake.acs.washington.edu
