This ZIP file contains two binaries "jacl.exe" for MS-DOS and "jacl.elf" for Linux. The game can be run by either executing the binary then entering the name of the game file (eldor.jacl) or just typing "jacl eldor.jacl" from the command prompt. The game can be saved by typing "save " and restored typing "restore " When using on a Linux system "eldor.jac" must be renamed to "eldor.jacl" and "jacl.con" to "jacl.conf".
