Re: tail recursion, again
; Our code simply will not run on the Symbolics without blowing the
; stack. As a result, my 3645 is nothing but an expensive terminal to a Sun.
I am catching up on a few days worth of mail so if this is redundant
please excuse me. The Symbolics drops into the debugger during recur-
sive function calls. First thought: What a wimpy machine. But in the
event that it saves your environment (like when someone modifies the
code to do a recursive nose dive) the meaning for it seems clear. A
Sun would just cons until it drops.
In short, the debugger is only trying to help you. Now, what to do if
you do not desire the debugger's help: Catch the offending form and
prevent it from running you into the debugger. The following code will
help you do this...
; (format *standard-output* "~%Growing the stack...")
(sys:proceed err :grow-pdl))))
