I second that book recommendation - it was *the* forth book back in the mid-1980s when IS-FORTH was written. It looks a bit cartoon-y at first glance but all the information is there in a readable format.

I have implemented Conway's Game of life with a nice example found at rosettacode.org. In lack of some commands in IS-FORTH I looked for ways around, most of a times the chance to find another way is good in Forth. VALUE / TO is replaced by a normal variable with @ and !. The other point is the at-xy, which is only AT in IS. And last the S" StringValue" is replaced by " StringValue" COUNT, which also leaves the count and the address on the stack.

It's loadable with the known procedure:
BUFFERS ON " A:GOL.4TH" NAME
LOAD-BUFFERS

After that the first 6 blocks have to be loaded (1 LOAD CR, 2 LOAD CR...6 LOAD CR). After all six pages are loaded the examples like "CLEAR 0 GLIDER SHOW CR" are working. But don't count rocket speed in execution

I wanted to use "->" to load the next block automatically, as described in the manual of IS-Forth. But it does not work -> "not found"

Hello Hexcaliburger.

I have tried to load the file, but Forth doesn't find it. What is your configuration?
