-- @usage print [ -l | -s ] parameter [ -l | -s ] parameter ...
-- @summary print the value of parameters
-- @start-doc
-- Print the value of a scalar (-s, default) or list (-l) parameters. With
-- the -s option, the value is first converted to a string which gives the
-- normal representation of value (list values are enclosed in square
-- brackers, e.g.,d::
--
-- ZBTest> print path
-- [/home/mrohan/xmpl/test-area, /home/mrohan/bin, /usr/bin, /bin]
-- ZBTest> print _platform
-- unix
--
-- With the -l option, the value is printed as a list. If the parameter is
-- not a list, it''s value is first converted to a list. E.g.,::
--
-- ZBTest> print -l l1
-- ZBTest> print _platform
-- unix
-- ZBTest> print -l _platform
-- 1) "unix"
-- ZBTest> print -l path
-- 1) "/home/mrohan/xmpl/test-area"
-- 2) "/home/mrohan/bin"
-- 3) "/usr/bin"
-- 4) "/bin"
