PROFESSIONAL GEM by Richard Karsmakers
Before you read on this article, I must tell you that I don't
know anything about C, and that this book is actually a GEM
course written for C users, so I don't know anything for sure
with regard to the level on which this book is written, and if
it's easy to use or not. I will just try to give a general
opinion. I hope you don't mind.
The whole course is written by Tim Oren and published by Antic as
a PD program. On the large usermeeting on September 20th 1986 in
Utrecht, the "Stichting ST" sold printed copies of it, which I
have hereby reviewed. If you want to obtain the PD disk, you
should read the magazine of "stichting ST" or have a look for a
club that sells the HCC Public Domain library (e.g. userclub
Eindhoven). We don't have this offering in our own Public Domain
It looks like Tim Oren did a great job; although he immediately
starts with programming examples and although he seems to think
the reader reads C like his native language, he sets everything
up like a regular teacher. He talks about windows, window
scrolling, dirty tricks (like using the GEM screen buffer to save
the parts of a screen under Alert Boxes and file selectors),
dialog handlers, resource structures, graphic modes, menus, VDI
graphics, GEM events & program structures, user interfaces, and
10 appendices with sample - C - programs to individual chapters.
When I glanced through "Professional GEM", I notices that Tim
writes in clear, crisp English with a touch of humour. The whole
is setup a bit informal which can work positively.
I think that this course can't be omitted if you're a dedicated C
programmer, since it offers you very much information and
programming hints & tips when using GEM in your C programs. It
seems, however, that you ahve to be in the possession of the
Digital Research C-Compiler do be able to work with this book.
Again, I am sorry for the lack of knowledge on my side, so I am
not able to write a proper review. But this articles (as well as
several others) had to written in quite a hurry, just before the
launch of ST NEWS (also because I went away the last week before
the launch - just imagine the hurry of making it all work on
Friday evening, Jaunari 2nd!).
The text of the articles is identical to the originals like they appeared in old ST NEWS issues. Please take into consideration that the author(s) was (were) a lot younger and less responsible back then. So bad jokes, bad English, youthful arrogance, insults, bravura, over-crediting and tastelessness should be taken with at least a grain of salt. Any contact and/or payment information, as well as deadlines/release dates of any kind should be regarded as outdated. Due to the fact that these pages are not actually contained in an Atari executable here, references to scroll texts, featured demo screens and hidden articles may also be irrelevant.
