I can’t get the helloworld.fs to run without errors. I am using gforth 0.7.3 on debian linux
This is what I get using the example file from the book’s source code zip file.

gforth code/forth/helloworld.fs

in file included from *OS command line*:-1
code/forth/helloworld.fs:5: Undefined word
>>>"Hello<<< World" TYPE CR
