Can "wcols" be used any way for writing a variable of type:

You can use dog() to split the piddle into single
columns that can then be written via wcols. However,
you'll get the numeric code for the characters and
not the letters. Here is something cooked up with
wcols through a pipe to generate the actual words.
pdl> use PDL::Char
pdl> $names = PDL::Char->new( [ 'hello', 'world', 'today' ] );
pdl> p $names
pdl> p $names
[ 'hello' 'world' 'today' ]
pdl> wcols $names->mv(0,-1)->dog, '| perl -ne "@c = split ; print map(chr,@c),
qq{\n}"'
hello
world
today
Cheers,
Chris
