;Task:
Present a program which emits the lyrics to the song ''[[wp:There Was an Old Lady Who Swallowed a Fly|I Knew an Old Lady Who Swallowed a Fly]]'', taking advantage of the repetitive structure of the song's lyrics.
This song has multiple versions with slightly different lyrics, so all these programs might not emit identical output.

We start with a collection of reusable phrases stored as a linked list. We then build up the sequence of indices into that list necessary to produce the song (this step is largely programmatic, because of the repetitive nature, although some of the verses require special case handling). Finally we iterate over the indices and print out the associated phrases.

=={{header|Commodore BASIC}}==
The portion of the program that handles the lyric logic (the "No Sound" version) is universal and should work across all Commodore models. Since a sound chip is available in Commodore BASIC on the C64, Plus/4, and 128, it is not difficult to take advantage of this. The 64 and Plus/4 versions demonstrate a very rudimentary music player based on the syntax used for the Commodore 128's PLAY command (thus making the data statements nearly identical in those three versions.)
The music is not quite as procedural as the lyric strings, since the music is tailored to the unique number of syllables for each phrase, however, each verse does utilize three basic music phrases that can be iterated through.

===Commodore 128===
BASIC 7.0 on the Commodore 128 features a robust PLAY command which will interpret strings of macro commands for commanding the SID processor. This all but eliminates the bulk of the note playing routines. Note the data statements are slightly different as the macros for note duration are different. The 128 uses '''i''', '''q''', and '''h''' for ''eighth'', ''quarter'', and ''half'' notes respectively, while the 64 and Plus/4 examples were coded to use '''8''', '''4''', and '''2''' as it was simpler to use for math operations, rather than an additional look-up table.

This version isn't as compressed as some of the others but it is very straightforward to modify. Just add a new long and terse verse entry and amend the line marked order. This uses a feature of Icon/Unicon that allows procedures to be called with a list datatype instead of an argument list, so we just pre-build argument lists for printf.

Here is somewhat verbose program showing a different approach.
The idea is to start with the last two verses of the song, and then work backwards to produce the earlier verses. This is done by recursively pattern matching on the song to extract text and produce the earlier verse, which is then prepended to the song.
The later verse does not contain one key piece of information we need to produce the prior verse: the animal-specific answer line for the prior animal. So we look this up by scanning a text which serves as a table.
The recursion terminates when the second pattern case matches the first verse: the third line is "Perhaps she'll die". In this case the song is not lengthened any more, and a terminating flag variable is bound to true.
Note one detail: in the first verse we have "... don't know why she swallowed the fly". But in subsequent verses it is
"that fly" not "the fly". So we do a lookup on the fly also to substitute the appropriate line, and in the fly case we skip the original line (see the first <code>@(maybe)</code>).
