FOIL was the name for two different programming languages.
CAI style language
The first FOIL was a CAI language developed at the University of Michigan in 1967. A programming language is an Artificial language that can be used to write programs which control the behavior of a machine particularly a Computer. The University of Michigan Ann Arbor ( U of M, U-M, UM or simply Michigan) is a top-ranked Coeducational public research The acronym stood for File-Oriented Interpretive Language and it was very similar to other CAI languages like COURSEWRITER and PILOT. The name PILOT is an Acronym, and stands for P rogrammed I nstruction L earning O r T eaching. However, it tried to make the language somewhat block-structured using whitespace which ended up making the language vaguely similar to BASIC or ABC. In Computer programming, BASIC (an Acronym for Beginner's All-purpose Symbolic Instruction Code) is a family of High-level programming languages ABC is an imperative general-purpose Programming language and programming environment developed at CWI, Netherlands by Leo Geurts
Example
: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
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 Rosenbloom and was based on Forth. Forth is a structured, imperative, stack-based, computer Programming language and programming environment
