Passing .lsp variables to command calls

Has anybody figured out how to pass the CONTENTS
of a variable that contains a list of data (say x & y of several points for
example) to a command call ? command "pline" PNTLIST "") where PNTLIST is
a
list of variables - each containing a x & y value.
Actually, I have this problem in similar conditions where
the command interpreter wants to read the variable name
literally instead of using its contents as the answer to a prompt it has
made.
Thanks, Scott

 

(command "pline")
(foreach n ptlist)
(command n))
(command "")

 

Actually, I have this problem in similar conditions where

made.

Variable passed to the (command) function are evaluated as they are in any
lisp expression. They're not taken literally unless you quote the variable
name.

The problem may be that you're not passing the correct type of data, as in
this case. You can't pass a list of points to a prompt for a point, you have
to go through the list and pass each point separately.

A good way to see what's happening with the command function is to set
cmdecho=1 so you can see what the prompts and errors are actually saying.
