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.

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.

=={{header|Objective-C}}==

The de facto Objective-C "Hello, World!" program is most commonly illustrated as the following, using the NSLog() function:

 

#import <Foundation/Foundation.h>

 

}

}

 

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>

 

}

}

 

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>

 

}

Or call the free println() function with the String as the argument.

println("Hello world!")

To generate a document that shows the text "Hello world!":

 

/Helvetica 20 selectfont

70 700 moveto

(Hello world!) show

 

If the viewer has a console, then there are the following ways to display the topmost element of the stack:

 

 

will display the <i>string</i> "(Hello world!)";

 

 

will display the <i>content</i> of the string "(Hello world!)"; that is, "Hello world!";

 

 

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:

 

/Helvetica 20 selectfont

70 700 moveto

show % prints to document

1 0 div % provokes error message
