K-APL Dictionary

This page is incomplete.

This page contains information on the translation of APL code to K and vice versa.

Due to major differences in APL and K's array models, some of these may not be completely accurate. A star symbol(*) will be placed next to these entries. K9 will not be added here until it is finalized.
