=================~INTRODUCTION~================= Welcome to Open BASIC, a simple text-based language. Open BASIC is easy to use but can support the most complex of programs! Because it is a high-level language with minimal syntax, you won't have to worry about using the wrong data type or finding the missing semicolon somewhere on line 97. Open BASIC's easy-to-read manual contains everything you could possible want to know combined with plentiful examples, so what are you waiting for! Start programming with Open BASIC today! I would like to thank @oblatespheroid for making Hull, the project which I based the UI off of. ====================~MANUAL~==================== In Open BASIC every line of code contains a command and (in some cases) an argument, similar to assembly language. Below is listed every command. Examples for how to use them will be provided. =====================~PRINT~===================== print [argument] - appends [operand] to output. Input: print Hello, world! Output: Hello, world! =====================~SLEEP~==================== sleep [number] - pauses for [number] seconds. Input: print 3 sleep 1 print 2 sleep 1 print 1 Output: 3 (1 second pause) 2 (1 second pause) 1 =====================~STOP~===================== stop - aborts execution of the program. Input: print sham stop print wow Output: sham ===================~COMMENTS~=================== //comment - place two slashes at the beginning of any line to make it not run Input: print sham //print wow Output: sham ====================~DELETE~==================== delete [number] - deletes the output at line [number] Input: print sham print wow delete 1 Output: wow =================~EDITING TRICKS~================= * Let's be honest, the Scratch editor is a lot better. I recommend going inside the project and editing the list directly. * Delete all lines at once by pressing the delete button and entering all. * You can also enter last to delete the last line. * Later, you learn that this also works on commands such as replace and insert. ====================~RANDOM~==================== \d - random number 0 to 9 (must be part of operand!) \b - random number 0 to 1 (must be part of operand!) Input: print Random Digit: \d print Random Binary Number: \b Output: Random Digit: 7 Random Binary Number: 1 Output: Random Digit: 4 Random Binary Number: 0 =====================~GOTO~===================== goto [number] - goes to line [number] Input: print this is line 1 goto 4 print this is line 3 print this is line 4 Output: this is line 1 this is line 4 Input: //prints a bunch of random digits print \d\d\d\d\d\d\d\d\d\d //restarts program from beginning, causing infinite loop goto 1 Output: 8051189042 2797639811 0186726652 ... (this will go on forever until you click the pause or stop button) ====================~REPLACE~==================== replace [number], [argument] - replaces line [number] in output with [argument] Input: print sham print wow sleep 1 //replace actually accepts 2 arguments separated by a comma replace 1, wow Output: wow wow ==================~LINE NUMBER~================== \n - gets current line number ====================~INSERT~==================== insert [number], [argument] - inserts [argument] before line [number] Input: print line \n print line \n //will get pushed to line 4 print line \n sleep 1 //will appear in line 3 of output insert 3, shamwow Output: line 1 line 2 shamwow line 3 ===================~VARIABLES~=================== set [variable] = [argument] - creates or sets a variable [variable] equal to [argument] Input: //variables replace all cases of their names surrounded by percent signs with their values // to display percent signs normally, use \% set hi = hello print %hi% set hi = 5 print %hi% Output: wow =====================~MATH~===================== add [variable], [number] - adds [variable] to [number] and stores it back into [variable] sub [variable], [number] - subtracts [variable] by [number] and stores it back into [variable] mul [variable], [number] - multiplies [variable] by [number] and stores it back into [variable] div [variable], [number] - divides [variable] by [number] and stores it back into [variable] Input: set var = 2 //2 + 5 = 7 add var, 5 print %var% //7 - 3 = 4 sub var, 3 print %var% //4 * 5 = 20 mul var, 5 print %var% //20 ÷ 2 = 10 div var, 2 print %var% Output: 7 ===============~DESCRIPTION LIMIT~=============== lol I reached the maximum size for a Scratch project description, so the rest of the manual can be found inside of a comment. 1. Click "See inside" 2. Click "Stage" 3. Scroll down until you get to the section on input 4. Have fun programming! :)
