Finished a "teach yourself" book, what next?

[Jacob Oost]

Should I get some more general books, like "advanced self-teaching," or
can I start on specialized books like "Linux game programming?"

Any book recommendations ?

But not, originally, in C. Advent was written in Fortran. The
original Infocom games were written in ZIL, which was a kind of
MDL, which was a Lisp-like language. I've no idea what their
'terps were written in.

The original code in MDL is, as far as I can tell, still a trade
secret, after more than 25 years.
I have the code for what I know as dungeons, aka Zork on my site.

It is in fact a 1991 source intended for MSDOS, but after
conversion to Unix text files, it compiles perfectly on Linux,
gcc. It is a testament to the practical portability of C.
I didn't want to look into the source (I want to play it, and
don't want spoilers) but I didn't need to. So I don't know
whether it is a good idea to study it.

The secrets are in the encoded .dat file, so reading the source
won't spoil your fun. At a first glance it seems fairly nicely
organized, but could do with advancing to C89 standards. Lots of
warnings under -ansi -pedantic, but none extremely serious, and the
result compiles and runs under DJGPP/windoze.

The original code is in ZIL, not in MDL (there are quite a few
differences), and they aren't so much a trade secret as simply lost in
the mist of times.

You do realise that the original was in Fortran for a DEC, more than ten
years earlier? A Fortran version is TTBOMK still available from the IF
Archive.

True; the Fortran version is not quite as portable. Never mind the
original Advent: that required you to save a core file if you wanted to
change the settings...

A text adventure is actually a good example of a fairly complex program
that can be written entirely in ISO C, if you don't care about the
looks.

Ho-hum. I must correct myself. The original for Dungeon _was_ written in
MDL. The originals for the separate Zorks and subsequent Infocom games
were in ZIL, though, and do appear to be lost rather than kept secret
(as, AFAICT, is the original Dungeon). The Fortran version appears to be
later than that.

What does this line mean (from your website):
"My modification to the source code of dungeons are in the public
domain. This mainly amounts to replacing pairs by only and selection a
scroll mode in the Makefile"
