'''FOIL''' was the name for two different [[programming language]]s.

==CAI style language==
The first '''FOIL''' was a [[Computer-assisted language learning|CAI]] [[programming language|language]] developed at the [[University of Michigan]] in 1967. The acronym stood for File-Oriented Interpretive Language and it was very similar to other [[Computer-assisted language learning|CAI]] languages like [[COURSEWRITER]] and [[PILOT]]. However, it tried to make the language somewhat block-structured using whitespace which ended up making the language vaguely similar to [[BASIC]] or [[ABC (programming language)|ABC]].

===Example===
<pre><nowiki>
 :START COUNT=0
 TY Enter the number of times you want to repeat the statement:
 ACCEPT
 MAX=NUMBER.(1)
 :LOOP
 TY This loop has run #COUNT times it will terminate when it runs #MAX times
 IF COUNT<MAX,
    COUNT=COUNT+1
    GO TO :LOOP
 TY Do you want to do this again?
 ACCEPT
 IF 'yes', GO TO START
 IF 'no' GO TO FINISH
 :FINISH
 TY Goodbye!
 STOP
</nowiki></pre>

==Music generation language==
The second '''FOIL''' was a music generation language for the Touché computer instrument in 1979. The Touché was a keyboard that had digital tone generation and allowed you to program software for performances. The acronym stood for Far Out Instrument Language and was succeeded by MetaFOIL and FOIL-83. The language was developed by [[David Rosenboom]] and was based on [[Forth (programming language)|Forth]].
