How do you open a saved Qbasic file in QBASIC itself to edit it?
IF THE QBASIC IDE/INTEGRATED DEVELOPEMENT ENVIRONMENT *IS* ALREADY OPEN Inside of QBASIC IDE/Integrated Development Environment...; you load in QBASIC programs as follows... 1. Use your mouse to click the QBASIC Menu option being seen top right... File > Open ...then, browse through the file list box to load your chosen program file. 2. Alternatively, you can also use keyboard short cut... [ALT]+[F], this opens up the file menu...then, press [O] ...does exactly the same as above IF THE QBASIC IDE/INTEGRATED DEVELOPMENT ENVIRONMENT IS *NOT* ALREADY OPEN 3. Another way is to open up a command line window prompt: (>)... Click [Start] button ...then, type: Command .../or, type: Cmd ...at least, one of the above should work... ...and, run the QBASIC program from there... by typing in after the command line prompt: (>)... c:\> cd, means, change directory folder... cd C:\pathToQbasic For example the file path name to where my version of QBASIC is stored here... c:\basic\qb64 So, I would first change to this folder directory by typing in after the prompt: (>)... c:\>cd c:\basic\qb64 ...this changes my command line prompt: (>) to say... c:\basic\qb64> Inside of the [qb64] folder directory, I wrote a very simple program called: hw.bas ...which contains the following single line of code... PRINT "Hello, world!" I can launch both the QBASIC program: [qb64.exe]/and, at the same time load in my chosen program file: [hw.bas], by typing after the command line prompt: (>)... C:\Basic\qb64>qb64 hw.bas ...the QBASIC program instantly loads: [qb64.exe]/with the program file [hw.bas] already being displayed inside of the Editor Screen. Next, I only need to press function key [F5] to RUN/make that program file execute... QBASIC Output Screen... Hello, world! Press any key to continue...
How do you download QBasic?
In order to Download Qbasic you may do one, both or none of these two things: 1.) Go to "http://www.softpedia.com/get/Programming/Coding-languages-Compilers/Qbasic.shtml" and click download or 2.) use "Google.com" with the keywords Qbasic free download to find another website with a free qbasic downlaod.
Find the power of a positive integer in qbasic?
PROGRAMMING LANGUAGE: QBASIC/VERSION: QB64 ...Program code... intNum% = 2 CLS PRINT "PROGRAM: POWERS OF N/(N ="; intNum%; ")" PRINT FOR intEachLoopNum% = 0 TO 10 PRINT intNum%; " ^ "; intEachLoopNum%; " = "; intNum% ^ intEachLoopNum% NEXT ...Output... 2 ^ 0 = 1 2 ^ 1 = 2 2 ^ 2 = 4 2 ^ 3 = 8 2 ^ 4 = 16 2 ^ 5 = 32 2 ^ 6 = 64 2 ^ 7 = 128 2 ^ 8 = 256 2 ^ 9 = 512 2 ^ 10 = 1024 *NOTE*: In QBASIC the mathematical symbol: ^...means 'raise to the power of'; thus, 2 ^ 3; actually means raise the number 2 to the power of 3/or, 2 x 2 x 2.
What characteristics in quickbasic?
CHOICE OF EITHER 32 BIT/OR ELSE, 64 BIT QBASIC PROGRAM VERSIONS There are both 32 bit/64 bit QBASIC program versions. You have to select which is the correct version that will run on your own operating system. For example,... -> Windows 95/98/XP, runs the 32 bit version(s) -> Windows 7 runs the 64 bit version CHOICE OF EITHER QBASIC 'INTERPRETER'/OR ELSE, 'COMPILER' VERSIONS QBASIC Version 1.1 was the original version; however, it is 'interpreter' only. This means you CANNOT use it to create stand alone [.exe]cutable files with. QBASIC Version 4.5 is a 'compiler' version; which CAN be used to create stand alone [.exe]cutable files with. QB64 is the 64 bit 'compiler' version which runs on 64 bit platforms; it can also be used to create stand alone [.exe]cutable files with.

Is qbasic a high level language?
The QBASIC program actually comes in 2 different flavors... A> QBASIC interpreter program: QBASIC Version 1.1 B> QBASIC compiler program: QBASIC 4.5/or, QB64/or, -etc. ...so, the answer is that this programming language comes in both forms: 'interpreter/compiler' versions; and, you have to select which of these you would prefer to download and use. *NOTE*: The compiler version of the language tends to be much larger; whereas, the interpreter version of the language tends to be small/very compact, indeed; thus, the interpreter tends to take up far less disk space. Many people start off their programming career by using QBASIC version 1.1 'interpreter' program; in order to learn 'how to' program. The interpreter version of the program can only create plain text (.bas) files; the which code CANNOT be shared with others; (not unless the persons who you are sharing this type of code with do already have a copy of the QBASIC interpreter program installed on their own computer). Then, later on, down the line...when they have become fully capable programmers themselves; they go and download a QBASIC 'compiler' program version, instead; which will allow them to go and create stand alone (.exe) program files that they can share with anybody. This is because (.exe) program files can RUN/execute entirely independently of the QBASIC program itself.
