APLBUG¶

We have received two recent issues of the APLBUG newsletter with brief papers as well as reports on their recent meetings. The March newsletter contains a solution to the Loss Carry-Forward problem raised in VECTOR Vol.2, No. 1. Tibor Horvath’s function is reprinted in the “Surely There Must Be A Better Way” column. The April issue reports on “Object Oriented Programming in APL” and how to overcome date problems for the year 2000 – and for the next 2 billion years provided the Earth’s rotation is unchanged. APLBUG membership costs $15 and applications should be sent to Curtis A Jones (see address list below).

APL Quote-Quad¶

Volume 16/3 of Quote-Quad contains a mix of notices, product news, articles, reviews, algorithms and recreation. The articles cover a Boolean Array Based Algorithm, Emulating Prolog, Trees and Networks using APL2, and an APL Workshop. Orders for APL Quote-Quad should be placed with:
