You should get in the habit of putting stack diagram comments on every line
of code - it will help you keep track of what you are playing with. By
convention, a stack diagram starting with $ indicates a addr,len string
pointer, which you should use in this code for clarity.
As best I can tell without stack diagrams, you are generating strings of the
form "foo: set-foo foo ! ; foo", and it's probably barfing on "foo:" . I'm not
sure what this is supposed to accomplish.
What I'm trying to do is create a new word. The new word's name will be set-_variable_name_. What would be another way to create a new word inside another word?
Replace the "eval" with a "type" and you should be able to see what it's
generating.
I tried your suggestion, but everything looked just fine. The problem shows up at compile-time. Using this code:
variable dog
: myword
4 -> dog
;
What the code should create at compile-time is this:
: myword
4 set-dog
;
but creates this instead
: myword
4 : set-dog
;
The problem is with the extra colon between the 4 and the set-dog word. I need a way to eliminate it from the myword word. Other times the compiler will say the word set-dog is undefined. Any clue how to fix this problem?
