Editing SNOBOL (section)

== Example programs ==

The "Hello, World!" program might be as follows...

<syntaxhighlight lang=snobol>
          OUTPUT = "Hello, World!"
END
</syntaxhighlight>

A simple program to ask for a user's name and then use it in an output sentence...
<syntaxhighlight lang=snobol>
          OUTPUT = "What is your name?"
          Username = INPUT
          OUTPUT = "Thank you, " Username
END
</syntaxhighlight>

Use :S (branch on successful match) to choose among three possible outputs...

<syntaxhighlight lang=snobol>
          OUTPUT = "What is your name?"
          Username = INPUT
          Username "J"                                             :S(LOVE)
          Username "K"                                             :S(HATE)
MEH       OUTPUT = "Hi, " Username                                 :(END)
LOVE      OUTPUT = "How nice to meet you, " Username               :(END)
HATE      OUTPUT = "Oh. It's you, " Username
END
</syntaxhighlight>

To continue requesting input until no more is forthcoming...

<syntaxhighlight lang=snobol>
          OUTPUT = "This program will ask you for personal names"
          OUTPUT = "until you press return without giving it one"
          NameCount = 0                                            :(GETINPUT)
AGAIN     NameCount = NameCount + 1
          OUTPUT = "Name " NameCount ": " PersonalName
GETINPUT  OUTPUT = "Please give me name " NameCount + 1 
          PersonalName = INPUT
          PersonalName LEN(1)                                      :S(AGAIN)
          OUTPUT = "Finished. " NameCount " names requested."
END
</syntaxhighlight>
