Hi everyone,

I want to get some data from
a user, that I want to put in an
array.. well the first one is filename
and the rest are a bunch of numbers
which are sepparated by -i and -o
options.

inFile = ARGV[0]
myArr = -i params
myArr2 = -o params

Any help appreciated.
Ted.

Cool, but now I'm having some trouble transforming the array from:

["0", "1", "2", "3"] to [0,1,2,3].. how can I do this?
