Here it is. The attached file contains version 5 of the distributions package as well as a PDF with instructions for the Normal, Student, Chi² and Fisher distribution. Also included are instructions for some additional functions, while the part that handles the discrete distributions (Binomial, XEQ O and Poisson, XEQ P) is still missing.

The Binomial and Poisson quantile functions use the 35s solver, so you'll see RUNNING...SOLVING....RUNNING before the result is returned. Here X holds the quantile, Y has the corresponding CDF and Z holds the CDF of x–1. This way you can check the result and see how close a continuous (real) quantile is to the adjacent integers. Note that the lower and uppers CDFs for the discrete discrtibutions do not sum up to 1 because they are P(X≤x) and P(X≥x), which means that PMF(x) is part of both sums.

All this requires extensive testing, so load the .ep file into your 35s emulator and see what you get. There may and will be errors, so I'll appreciate all your error reports. Thank you in advance for all corrections and suggestions.
