QBASIC code/Editor Screen (Press key [F5] to make the program RUN/execute...) ==== (Pressing any key returns you straight back to the Editor screen; where you can either chose to further Edit/Re-Run/or else, Save your program.) Here is another example. CLS COLOR 15, 4, 14 PRINT "Press any key to continue" DO WHILE INKEY$ = "" LOOP FOR c = 1 TO 20 COLOR c, 0 PRINT "Replace this with the name you want to display" NEXT c COLOR 15, 0 END
EXAMPLE 1 The QBASIC program will, automatically, *capitalize* any reserved 'keyword' which it finds once you've already gone and typed in a line of code; and, then, at the end of that code line, do finally press the [RETURN/ENTER] key...to confirm what you've just gone and typed in. A keyword might be say the PRINT command statement...so, if I were to type inside of the QBASIC editor the following line of code... print 1+1 ...then, the moment I press the [RETURN/ENTER] key when I get to the end of that line...the QBASIC interpreter program will, automatically, change the 'lower case' word: print...to become all UPPERCASE, instead; QBASIC Editor will display the previous line of code I typed in as being... PRINT 1+1 ...thus, I am able to tell immediately that PRINT is a special reserved 'keyword'/or, command statement which the QBASIC program, quite clearly, recognizes and understands. This also helps me the programmer to know if I actually typed in that 'keyword' either correctly/or, incorrectly; if wrong...and, the program did NOT automatically capitalize it...; then, I know I must have either accidentally 'misspelled' the keyword/or, must otherwise have done something to go get it wrong...?! EXAMPLE 2 If I were to type in to the QBASIC Editor program the following line of code using all 'lower case' letters... x=10: if x=10 then print "ten" else print "NOT ten" ...and, then, when I've reached the end of that line of code, press [RETURN/ENTER] key to confirm my code entry; the QBASIC interpreter program will, automatically, respond by capitalizing any reseved 'keywords' that it finds; then, QBASIC Editor displays the line of code I typed in as being... x=10 : IF x=10 THEN PRINT "ten" ELSE PRINT "NOT ten" Looking at this newly capitalized line...it tells me that... IF/THEN/ELSE/PRINT...are all QBASIC reserved 'keywords'. NOTE: Whatever is a string a text that is written in between double quote marks: ("") will be totally unaffected by such capitalizing; instead, text strings will be printed out, quite literally, 'as is'. FINAL NOTE There are far too many QBASIC 'keywords' for me to go and list here; possibly, a couple hundred...! QBASIC has many 'keywords' that it uses; if you wish to see what ALL of these keywords are; then, from inside of the QBASIC Editor program itself...do a combination key press of: [SHIFT] + [F1]...and, there you will see the Help file...that shows each 'keyword' you can use to write QBASIC programs with; as well as, offering a clear explanation/it shows 'example codes' demonstrating exactly how each of these 'keywords' should be used; just do 'copy & paste'/then, RUN the program to follow these examples along.

WRITE A PROGRAM TO CONVERT A 2-DIGIT bcd NUMBER INTO HEXADECIMAL
34
Write a program that calculates the area of a triangle in QBASIC
a triangle then a square :)
you do this 10 print "0112358132134" use the whole of the thing
Yes I can. I did it in QBasic about 15 years ago.
the extensions of qbasic are that, there are only 80 pixels to write in the qbasic
Cls input "enter two no.s ",a,b sum=a+b print "sum = ";sum end
I think it's <>
dim a input a
just full it up when its at the E
write a c program to accept a number and generate a square root cube and exponential values
you cant
happy birthday...
