APL2C
APL2C is a nested APL implementation consisting of a complete interpreter, and a compatible compiler with some restrictions. It supports much of the functionality specified by the Extended APL standard ISO/IEC 13751:2001, including some features such as the Commute and Rank operators that were not widely supported at the time of its initial release.[1] Development of APL2C began in 1991, and it was used in commercial applications before its public release. The compiler and its use in medical image analysis were presented at the 2000 APL conference.[2][3] The implementation was later offered as a trial version, with a tutorial on using it presented at the 2001 APL conference.
APL2C's compiler generates C code that calls functions for primitives and other operations such as loading variables, removing interpreter dispatch overhead. Compiling allows a program to be distributed as an executable file, and allows the APL code to inter-operate with C. It restricts some dynamic functionality: compiled programs can't dynamically create APL functions with ⎕FX, and can't pass arrays (rather than functions) as operands to user-defined operators.
