Applesoft BASIC
Output isn't consistent with the task's requirements: mixed case
Important Note: Although Applesoft BASIC allowed the storage and output of mixed-case strings, the ability to enter mixed-case via the keyboard and to output mixed-case on the default display was not offered as standard equipment on the original Apple II/II+. Since Applesoft WAS the default programming language for the Apple II+, perhaps some flexibility in the task specification could be offered, for this and for other systems that lacked proper mixed-case I/O capabilities in at least one popular configuration.

"BEGIN" is a "special pattern" - code within "{}" is executed before the input file is read, even if there is no input. "END" is a similar pattern, for after completion of main processing.
END {
print "Hello world!"
}
For a file containing data, the work can be done in the "body". The "//" is "match anything" so gets the first data, the "exit" halts processing the file (any "END" would then be executed). Or instead of //, simply 1 is true.
// {
print "Hello world!"
exit
}
For a "single record" file.
// {
print "Hello world!"
}
For a "single record" file containing - Hello world! -. The "default" action for a "pattern match" (the "/" and "/" define a "pattern" to match data) is to "print" the record.

Brainfuck
To print text, we need the ascii-value of each character to output.
So, we wanna make a series of round numbers going like:
10 close to newline and carriage return 30 close to ! and SPACE 40 close to COMMA 70 close to G 80 close to W 90 close to b 100 is d and close to e and l 110 close to o 120 close to y
forming all the letters we need if we just add up a bit
Commented version:
+++++ +++++ First cell 10 (its a counter and we will be "multiplying")
[
>+ 10 times 1 is 10
>+++ 10 times 3 is 30
>++++ etc etc
>+++++ ++
>+++++ +++
>+++++ ++++
>+++++ +++++
>+++++ ++++++
>+++++ +++++++
<<<<<<<<< - go back to counter and subtract 1
]
printing G
>>>> + .
o twice
>>>> + ..
d

b
< +++++ +++ .
y
>>> + .
e

<<<< ++++ .

It can most likely be optimized, but this is a nice way to show how character printing works in Brainfuck :)

By default some Commodore computers boot into uppercase/graphics mode (C64, C128, VIC-20, Plus 4, etc.) while others (PET, CBM etc.) boot into lowercase/uppercase mode. Therefore, depending on machine used, the CHR$(14) may or may not be required to switch into mixed-case mode.

DDNC
DDNC can only output to a single 7-segment LED display digit, so first we must convert each character into its 7-segment equivalent numerical value.
The three horizontal bars are assigned bits 6, 3, and 0 from top to bottom. The top two vertical bars are assigned bits 5 and 4 while the bottom two vertical bars are assigned bits 2 and 1 from left to right.
Because DDNC can only interpret literals in decimal, each binary number was converted and stored in consecutive memory cells starting at cell 10.
The code can be divided into three sections. The first stores the character numbers in order in an array. The second sets up the loop by loading a delay of 500 milliseconds to slot 3, the start address of the character array in memory to slot 2, and the number of times to loop (14) plus one to slot 5. The third section starts the loop of displaying the characters, waiting for the delay time, incrementing the pointer, decrementing the counter, and checking if the counter is negative to know whether to continue the loop.

The EDSAC did not support lower-case letters. The method used here is to include a separate O order to print each character: for short messages and labels this is quite adequate.

Fish
Standard Hello, world example, modified for this task:
!v"Hello world!"r!
>l?!;o
Explanation of the code:
!v" jumps over the v character with the ! sign, then starts the string mode with " .
Then the characters Hello world! are added, and string mode is closed with ".
The stack is reversed for printing (r), and a jump (!) is executed to jump over the ! at the beginning of the line and execute the v. ([[Fish]] is torical)
After going down by v, it goes rightwards again by > and this line is being executed.
This line pushes the stack size (l), and stops (;) if the top item on the stack is equal to 0 (?). Else it executes the ! directly after it and jumps to the o, which outputs the top item in [http://en.wikipedia.org/wiki/Ascii ASCII]. Then the line is executed again. It effectively prints the stack until it's empty, then it terminates.

HQ9+ output isn't consistent with the task's requirements (and is probably incapable of solving the task).

Technically, HQ9+ can't print "Hello world!" text because of its specification:

-

-

-
- : Increase Pointer (useless!)

NOTE: Integer BASIC was written (and hand-assembled by Woz himself) for the Apple 1 and original Apple 2. The Apple 1 has NO support for lower-case letters, and it was an expensive (and later) option on the Apple 2. This example accurately represents the only reasonable solution for those target devices, and therefore cannot be "fixed", only deleted.

Section Public
- main <- ("Hello world!\n".print;);
However, it may be more straightforward to use IO.print_string instead:

To get text output, compile the source file using NROFF and set output to the text terminal. If you compile using TROFF, you will get graphical output suitable for typesetting on a graphical typesetter/printer instead.
Because /.ROFF/ is a document formatting language, the majority of input is expected to be text to output onto a medium. Therefore, there are no routines to explicitly call to print text.

Objective-C
Works with clang-602.0.53
The de facto Objective-C "Hello, World!" program is most commonly illustrated as the following, using the NSLog() function:
#import <Foundation/Foundation.h>
int main() {
@autoreleasepool {
NSLog(@"Hello, World!");
}
}
However the purpose of the NSLog() function is to print a message to standard error prefixed with a timestamp, which does not meet the most common criteria of a "Hello, World!" program of displaying only the requested message to standard output.
The following code prints the message to standard output without a timestamp using exclusively Objective-C messages:
#import <Foundation/Foundation.h>
int main() {
@autoreleasepool {
NSFileHandle *standardOutput = [NSFileHandle fileHandleWithStandardOutput];
NSString *message = @"Hello, World!\n";
[standardOutput writeData:[message dataUsingEncoding:NSUTF8StringEncoding]];
}
}
Objective-C also supports functions contained within the C standard library. However, Objective-C's NSString objects must be converted into a UTF-8 string in order to be supported by the C language's I/O functions.
#import <Foundation/Foundation.h>
int main() {
@autoreleasepool {
NSString *message = @"Hello, World!\n";
printf("%s", message.UTF8String);
}
}

If the viewer has a console, then there are the following ways to display the topmost element of the stack:
(Hello world!) ==
will display the string "(Hello world!)";
(Hello world!) =
will display the content of the string "(Hello world!)"; that is, "Hello world!";
(Hello world!) print
will do the same, without printing a newline. It may be necessary to provoke an error message to make the console pop up. The following program combines all four above variants:
%!PS
/Helvetica 20 selectfont
70 700 moveto
(Hello world!) dup dup dup
= print == % prints three times to the console
show % prints to document
1 0 div % provokes error message
