Abstract

This paper tackles three areas of difficulty in APL. The first is the subjection to APL syntax of the work presently performed by system commands under user intervention. The second is the growing diversity of object types noted by Crick. The third arises from the matter of assigning functions raised by Iverson and Wooster. All three areas are addressed by proposed extensions to the definition and concept of functions. The extended definition is shown to incorporate workspaces, groups, workspace libraries, file subsystems and namespaces as special cases, and to make certain system commands redundant.
