Hi,
Working in CLM with a .clm file, getting confused with lisp, and I was hoping I
could get some help from lisp experts here.
I'm confused why collecting into a global list is not available from the second
loop, in ex. 1. I'm wondering if I'm not understanding something about scope.
Should the loops from ex. 1 be wrapped with something else like a "let"
statement?
I can access the global list by defining a function in ex. 2, but curious where
I'm going wrong in ex. 1?
ex. 1
(defvar mylist '(0.5 100.0 200.25 4000.0 1.0 0.33))
(defvar *test* '(nil))
(loop
for i from 0 to 10 by 1
for xx in mylist collect (random-element mylist) into *test*
finally (return *test*))
)
(loop
for i from 0 to 10 by 1
for yy in *test* ;the randomized list above does not seem available as
global here
do
(format t " ~A" yy)
)
------------------
ex. 2
(defvar mylist '(0.5 100.0 200.25 4000.0 1.0 0.33))
(defvar *test* '(nil))
(defun myfunc (somelist)
(loop
for i from 0 to 10 by 1
for xx in somelist collect (random-element somelist) into *test*
finally (return *test*))
)
(loop
for i from 0 to 10 by 1
for yy in (myfunc mylist)
do
(format t " ~A" yy)
)
