2 Source Code Availability All of the source code in this volume, and
some that is not, is available from the author for $20. The author is
also interested in learning of any errors that may be found, though care
has been taken in the construction of the modules to minimize the
possibility of their occurence. Any other comments, suggestions,
recommenda- tions, questions, or experiences with the use of these
modules would also be of interest. The reader may contact the author via
the publisher at the following address: C. Lins: Modula-2 Source Code
c/o Springer-Verlag 815 De La Vina Street Santa Barbara, CA 93101 USA As
of February 1989, source code is available on two 3. 5" Macintosh
diskettes (800K HFS format) for Bob Campbell's Modula-2 compiler for
MPW(formerly TML Modula-2) and the MacMETH Modula-2 compiler from ETH
Zurich. The author intends to port this software to both the SemperSoft
and MetCom Modula- 2 compilers on the Macintosh. For the IBM PC (and
compatibles) the software is available for TopSpeed Modula-2 (a product
of JPI). The source code will soon be converted to work with Logitech's
Modula-2 compiler as well as Stony Brook's Modula-2. Please mention your
hardware platform as well as the volume(s) in which you are interested
Development Environment The software for this volume was developed using
the MPW (Macintosh(TM) Programmer' s Workshop) version 3. 0 and Bob
Campbell's Modula-2 compiler ver- sion 1. 4d7.
