Forth local variable assigning variables

问题

I have a simple local variable in Forth:

: subtraction { a b } a b - ;

I would like to assign the output of

a b -

to another variable, say c.

Is this possible?

回答1:

TO works for both VALUEs and local variables, so:

: subtraction { a b | c -- } a b - to c ;
