I found a nice Adventure Game on an Excalibur 64 (and Aussie computer running CP/M 2.2) disk called "The Twilight Zone". It came compete with its C source code as well. However playing the game, it cant be completed due to an error found. The C code can be fixed but I have no idea what version of C was used to compile it. Near the start of the code it says
/* Compile by: c -k -f -s500 -w60 tz */
and right at the end it has
#include "stdlib.c"
Does anyone recognise this version of C that would allow me to re-compile to a working game?
Many thanks for any help
