Lisp Routine

(OP)
Given a variable defined as (setq a '(-10 -20 10 20))
Can you help me to find the Max or Min of a (i.e. using the variable a). I would appreaciate anything other than (max -10 -20 10 20).

RE: Lisp Routine

(apply 'max a) where is set to your list
'(-10 -20 10 20). Cheers.

RE: Lisp Routine

This should be the post......

(apply 'max a) where 'a' is set to your list
'(-10 -20 10 20). Cheers.....

RE: Lisp Routine

(OP)
Thanks it worked well, is there a command which can sort numbers i.e. (min - - - - - max) just like we can  sort letters alphabetically.

RE: Lisp Routine

For sorting numbers in Acad2000 and above, you can use
the following: (vl-sort x '<) where 'x' is the list of
numbers you want sorted from min to max.
