Abstract
This paper presents a set of structured control statements for APL and a preprocessor to implement them. The preprocessor translates structured APL functions into APL functions using the branch operator to replace the structured statements. The translation is based on finding keywords, such as IF and WHILE, appearing in syntactically valid places in the function. Since no modification of either the APL interpreter or APL syntax is required, the APL editor can be used to modify structured functions. The preprocesor also produces an indented listing that aids in the debugging of programs.
