Abstract
Printing APL dialects is, quite often, a frustrating task, for there is no simple method to convert the code itself into suitable output, for instance, PostScript or Portable Document Format. Generally speaking, printing of APL has relied on the interpreter itself, or perhaps converting the workspaces using an automatic transliteration scheme. In this article, I introduce a practical solution to the problem of printing APL dialects which does not require the use of the interpreter nor transliteration of workspaces provided a "source" file is available. After a typesetting solution described elsewhere [de Almeida, APL Quote Quad 34(2) (2004) 28] I implement a less complex, direct printing approach using a Type 1 (or outline) APL font, an encoding vector, and Gnu's a2ps, a program which converts files or standard input to PostScript, and I further provide an illustration of conversion of APL "source" into PostScript, ready for printout (or for visualization on the screen) using Morgan Stanley's A+ dialect.

Typesetting APL with LATEX: the APL front end APL2TEX
In this paper we present an APL publishing system for LATEX which supports typesetting of APL publications and documents in a mixed hardware, multiple vendor APL environment. It requires minimal maintenance and is in the public domain. The system has ...

Defining APL community: case studies, towards a revival of APL community
APL '00: Proceedings of the international conference on APL-Berlin-2000 conferenceI have been attending APL conferences for just under a quarter century now, and the one theme that runs through many conversations at all of them is how "APL is dying". Between conferences, I hear this time and time again, usually most loudly from ...
