Coding Snippets

The aim of these pages is to offer some guidelines for coding APL applications. The guidelines are offered as an aid to developing a consistent code style and there may well be room for debate regarding whether the style is necessarily optimal.

Some of the code samples are general and should be applicable to all (current) implementations of APL, others may be specific to only a subset of the various APL versions - this is indicated below.

Suggestions for topics which might be included should be sent to Dick Bowman.
