Short Takes

• This document is there as a placeholder for all modifications done. As a principle items are not suppressed or modified; new entries are added in chronological order.
• The current version is PCS 4.02 Patch level 1, dating 1993-dec-07. The Patch level number will be increased each time a bug is found and fixed.
• PCS is distributed freely in source and binary form. You can freely do whatever you want with this product, including modifying the source code for your own use.

  Some time ago, we were very proud of the quality of our source files (at least compared to TI distribution files). Now our version suffered from many partial revisions, and a general cleaning would have been necessary. Sorry, but we don't have time for this today...

• We are working hard on documentation...but please be indulgent. As PCS/GE is very close to TI's 3.03 release, we suggest you turn to Texas Instruments' documentation. You may order TI's manual at the MIT press. It's called:
  PC Scheme: Users Guide and Language Reference Manual, Trade Edition, TEXAS INSTRUMENTS, 416 pp, 1990, ISBN 0–262–70040–9. All our modifications should be documented either here, in the file MANUAL.TEX or in the reference card.

• We wrote a Quick Reference Card for PC Scheme/Geneva. The source file in TEX format is included in the distribution package. You should print it using a good laser printer (400 dpi or 600 dpi are much better than 300 dpi), and if available, on A3 paper, since it is pretty big (40 cm by 21 cm, i.e. 16 in by 8.3 in). If you find something unclear, or if something is not correct, please send an E-mail. We will soon print a thousand high-quality reference cards; if you are interested, send us a message.

• The authors assume no responsibility in case of damage due to a bug in PCS. Bug hunting and fixing is nevertheless an important activity for them. If you find a bug, please send a message to the E-Mail address below. You will be rewarded by an authentic Swiss present...

• The official FTP server is ``cui.unige.ch''. PCS is there in directory ``pub/pcs''. Different file formats are present:

  PCSCHEME.EXE

  The big archive, containing everything except the source code. It is an archive made into an executable file for convenience purposes. The compressor used is ARJ, though you won't need it.

  PCSCHEME.TAZ

  A UNIX tar-file, compressed with gzip. It contains exactly the same files as PCSCHEME.EXE.

  PCSCHEME.FIL

  The list of files in the tar archive.

  SOURCES.EXE

  Another big archive, containing all source files for PC Scheme/Geneva, for use with Borland C++ 3.1 programming tools; again, it is an archive made into an executable file for convenience purposes.

  SOURCES.TAZ

  A UNIX tar-file, compressed with gzip. It contains exactly the same files as SOURCES.EXE.

  SOURCES.FIL

  The list of files in the tar archive.

• PCS has its own mailbox: ``schemege@cui.unige.ch''. You are asked to use this address, so that developers know at a glance they receive mail concerning PCS.

  The developers themselves can be reached at ``lbartho@cui.unige.ch'' and ``mvuilleu@cui.unige.ch''.
