Conclusion

In this paper we have presented our solution to the APL typesetting problem: An APL publishing system consisting of a LATEX document style option and an APL front end. No additional fonts are needed. We have given short examples which demonstrate the usefulness of this approach. The system has already been used by the authors to prepare several articles published in APL Quote Quad, the journal of the APL user community.

METAFONT could be used to improve the printing quality of some symbols (cf. [Hohti, Kanerva 88]). However, it would be necessary to create a whole APL font family (different sizes and type styles) to obtain the flexibility of our system. We could incorporate special APL fonts without any change in the APL front end as soon as they become available.

The APL front end is currently implemented for APL2 and Dyalog APL and can be obtained from the authors. Further porting is intended. The LATEX document style option will be submitted to the Clarkson and Aston archives as well as to the German TEX server at Heidelberg.

The authors would appreciate comments and suggestions for the improvement of the style as well as comments with regard to APL symbols not available in this style.
