Hi all,
I'm now going through PAIP (chapter 6, match-if function) and there is
something the author uses but my CLISP v2.28 just doesn't grok. Simply
put, it boils down to:
[132]> (setq op '+ x 7 y 25)
25
[133]> (eval '(op x y))
*** - EVAL: the function OP is undefined
Why does EVAL evaluate x and y but doesn't evaluate op ?
Is this a problem with clisp or with the code from PAIP ?
Thanks in advance
Eli
