Ok. I did not know the prompt was configurable. >> 3) I noticed "evaluate" is working with null-ended string, ignoring >> completely the count on the stack. Not good. > >Is this an implementation feature? Does the count on the stack ever >not match the length of the string? I'm not sure what do you mean with the first question. As for the second question... sure. Forth string operators are all count based. The null will not appear on the end of the string unless you put it there yourself. Now, adding nulls to the end of the string is very easy with count based strings (as long as you are not working with a substring), and I have nothing against doing it. But having "evaluate" operate on null-terminated strings is the same as having strncmp operate on null-terminated strings: it's against standard and intent. -- Daniel C.
