I have two questions:
1- I'm trying to define a new type of variable, one that holds
someone else's CFA. Is there a command that can take a CFA off
of the stack and execute it?
2- How do define a compiler word without <BUILDS? I have a DOES>.
I thought of [COMPILE] :, but in my application it wastes space.
Thanks,
micha

DoVector In some Forths, there is a word, @EXECUTE, that optimizes the @ EXECUTE sequence. > 2- How do define a compiler word without <BUILDS?

You might have CREATE on your system. -- Andrew Scott andrew@idacom - or - {att, watmath, ubc-cs}!alberta!idacom!andrew
