What does the QBASIC automatically capitalize for you?

Answer 1

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.
