NUMBERCRUNCH II is on the way! I've been working steadily on a major upgrade to NumberCrunch, which I hope to have done and ready to sell for about $50 or so this summer. (By the way, if anyone out there has a suggestion for a good way for me to market this, I'm all ears...) NumberCrunch II already has (as of 3/90) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ • arrays, for example j={2,5,7} x = 1…10@.2 which sets x = {1, 1.2, 1.4, ... 10} y = sin(x)/x which takes sin(x)/x for each value of x y[j] = {y[2], y[5], y[7]} • Pascal-like programs, for example Function Integrate(theFunc, theMin, theMax, dx) var j begin j = theMin…theMax@dx # sets j = to an array Integrate = dx* sum( theFunc(j) ) end ( then if f(x) = x^2, Integrate(f,1,2,.01) gives .01*[ 1^2+ 1.01^2 + 1.02^2 +...+ 2^2 ] = 2.35835 ) • complex numbers and functions (sin, cos, exp, etc.) of complex arguments, • strings (so that the pascal-like programs can format their output), • multiple files open and multiple windows per file in the application, • externally compiled Xcod resources to perform specialized functions (like fast-fourer transforms,) • command completion, and it will have : ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ • matrices and higher dimension arrays, • units (kg, m, sec, etc.) • spread-sheet like entry of matrices and arrays, or entry from a data file • better graphics, including vectors and contour plots. So keep your eyes out for it. It'll be worth waiting for. (I hope). - Jim Mahoney 3/13/90
