Its used many times to introduce computer programming to people. Because of this, Logo is many times mistankly seen as very simple, while its quite complex, and equal to any other language. -- Usage When you open the script, you will notice two tabs, one with the Launcher, and one with the editor. Use ctrl + left/right to navigate between them. To launch a script (first tab), you select it in the list and press enter. Execution should start right away. Please note that some scripts might take a time to run, as they are interpreted in an interpreted language. To edit a script or create a new one, navigate to the seccond tab. Choose "New script..." to create a new script, or any other option to edit an existing script. The editor will appear. Navigation through the editor is very simple (arrow keys), and to save your script just press "escape". -- Key's Switch between editor and launcher : ctrl + left/right Launch/Edit a script : Enter Navigate in editor : up/down/left/right Insert tab : Tab -- Logo implementation The following primatives are implemented: butlasts, last, fput, bk, while, pick, cg, remainder, list, firsts, hideturtle, minus, word?, setc, sqrt, sety, cs, ifelse, do.while, modus, butfirsts, difference, cos, setxy, log10, lasts, wordp, if, output, for, until, sentence, thing, combine, sin, emptyp, notequalp, list?, print, remove, pu, round, random, setpc, circle, first, st, clean, setx, item, stop, se, rt, repeat, penup, lput, pendown, setpencolor, back, ht, fd, right, equalp, butlast, forward, repcount, do.until, word, left, debug, make, lt, show, notequal?, quotient, power, empty?, butfirst, equal?, product, number?, numberp, sum, listp, showturtle, int, tan, pd, xcor, ycor, heading, label, setlabelheight, setheading, local LogoMagic doesn't yet support array's and "?" stuff, but most needed stuff (such as lists, words, infix operators) are implemented. -- Credits Levak, Critor and Adriweb from TI-Planet Qwery.55 (also known as Fishbot) for pointing me to RPN.
