[PD] array read -resize according to file ?

[Miller Puckette]

Also, if the file has numbers on separate lines, you can use the "-cr" flag
to the "read" message to text to get each one on its own line in the
object - this should make it easier to manipulate.  But "array" objects are
much more efficient - it might be worth writing a loop that simply loads
the numbers from text into an array one by one at startup.

OTOH the "soundfiler" object really should be able to read/write ascii
numbers - that's been on my dolist for a decade or more.

cheers
