There's no need to push the link register because we are not writing a function that calls another function and it is not recursive. We also do not need to align the stack pointer because we are not even using the stack. Also we can use adr instead of ldr to load an address into a register. We do not need to generate a literal pool. We can also use an expression so the assembler calculates the length of the message. The following example works in Linux on the Raspberry Pi Zero 2 W using the gnu assembler and linker.
.global _start
.text
_start:
mov x8, #64 //64 is write
mov x0, #1 //1 is stdout
adr x1, msg //mov address of msg into x1
mov x2, #(msgend - msg) //msgend minus msg is the length of message
svc #0 //system call
mov x8, #93 //93 is exit
mov x0, xzr //0 is the exit code. xzr is the zero register
svc #0 //system call
msg:
.ascii "Hello world!\n"
msgend:
.align 4
The last example calculates the length of the string at compile time. It's fast, but not very convenient. The next example calculates the string length at run time. This is nice because we can call this function over and over again on different strings of different lengths. It does add a half dozen instructions and a loop to the code, so it runs a little slower. The Raspberry Pi Zero 2 W runs at a whopping 1 GHz ;) , so you'll never notice it with the human eye.

WRITE 'Hello world!'.
(cw "Hello world!~%")
Since there is no string data type in the language, a symbol (an identifier or 'character atom') must be used instead. When writing a symbol in source code, exclamation mark is an escape character that allows characters such as spaces and exclamation marks to be treated as part of the symbol's name. Some output functions will include exclamation mark escapes when outputting such symbols, and others, such as printc, will not.
(printc 'Hello! world!!)
The single quote in front of Hello! world!! makes it an expression that evaluates to the symbol itself; otherwise, it would be treated as a variable and its value (if it had one) would be printed instead.

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.

Developed on an Acorn A5000 with RISC OS 3.10 (30 Apr 1992)
Using the assembler contained in ARM BBC BASIC V version 1.05 (c) Acorn 1989
The Acorn A5000 is the individual computer used to develop the code,
the code is applicable to all the Acorn Risc Machines (ARM)
produced by Acorn and the StrongARM produced by digital.
In the BBC BASIC part of the program I have included:
OS_WriteC = &00
OS_WriteO = &02
OS_NewLine = &03
this is so I can write SWI OS_WriteC etc instead of SWI &0 to make the assembler more legible
(a) method1 - output the text character by character until the terminating null (0) is seen
.method1_vn00
ADR R8 , method1_string \ the ARM does not have an ADR instruction
\ the assembler will work out how far the data item
\ is from here (in this case a +ve relative offset)
\ and so will produce an ADD R8 , PC, offset to method1_string
\ a magic trick by the ARM assembler
.method1_loop
LDRB R0 , [R8], #1 \ load the byte found at address in R8 into R0
\ then post increment the address in R8 in preparation
\ for the next byte (the #1 is my choice for the increment)
CMP R0 , #0 \ has the terminating null (0) been reached
SWINE OS_WriteC \ when not the null output the character in R0
\ (every opportunity to have a SWINE in your program should be taken)
BNE method1_loop \ go around the loop for the next character if not reached the null
SWI OS_NewLine \ up to you if you want a newline
MOVS PC , R14 \ return
\ when I call an operating system function it no longer operates
\ in 'user mode' and it has its own R14, and anyway the operating system
\ is too polite to write rubbish into this return address
.method1_string
EQUS "Hello world!" \ the string to be output
EQUB &00 \ a terminating null (0)
ALIGN \ tell the assembler to ensure that the next item is on a word boundary
(b) method2 - get the supplied operating system to do the work
.method2_vn00
ADR R0 , method2_string \ the ARM does not have an ADR instruction
\ the assembler will work out how far the data item
\ is from here (in this case a +ve relative offset)
\ and so will produce an ADD R0 , PC, offset to method2_string
\ a magic trick by the ARM assembler
SWI OS_WriteO \ R0 = pointer to null-terminated string to write
SWI OS_NewLine \ up to you if you want a newline
MOVS PC , R14 \ return
.method2_string
EQUS "hELLO WORLD!" \ the string to be output
EQUB &00 \ a terminating null (0)
ALIGN \ tell the assembler to ensure that the next item is on a word boundary

"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.

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.

QThe 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. A more general (though slightly more involved) solution for printing strings is given at Hello world/Line printer#EDSAC order code.

!v"Hello world!"r!
>l?!;oExplanation 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 ASCII. Then the line is executed again. It effectively prints the stack until it's empty, then it terminates.

print 100,"Hello world!"Output to channels other than stdout goes like this:
write (89,100) "Hello world!"uses the format given at label 100 to output to unit 89. If output unit with this number exists yet (no "OPEN" statement or processor-specific external unit setting), a new file will be created and the output sent there. On most UNIX/Linux systems that file will be named "fort.89". Template:7*7

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);
}
}print_endline "Hello world!"#USE "course.lib"
PROC main (CHAN BYTE screen!)
out.string("Hello world!*c*n", 0, screen)
:disp("Hello world!");Or, using C-style function printf:
printf("Hello world!");package main
import "core:fmt"
main :: proc() {
fmt.println("Hellope!");
}"Hello world!" .(print "Hello world!")`Hello world!\n' print flushuse core {printf}
main :: () {
printf("Hello world!");
}- Output:
Hello world!
To print a String, either call its println() method:
main: func {
"Hello world!" println()
}Or call the free println() function with the String as the argument.
main: func {
println("Hello world!")
}Refer also to the Rexx and NetRexx solutions. Simple output is common to most Rexx dialects.
/* Rexx */
say 'Hello world!'We can use the same code as the Common Lisp example, but as a shell script.
#!/openlisp/uxlisp -shell
(format t "Hello world!~%")
(print "Hello world!")Output: Hello world! "Hello world!"
echo("Hello world!"); // writes to the console
text("Hello world!"); // creates 2D text in the object space

(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!) printwill 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
