Subject: Re: Capturing STDOUT from a system call (POSIX) into an array

Thanks for your quick reply. I realize that you don't even need to use
split. What I am missing is how to create a 2 dimensional array with
each line contents in an array assuming that they are separated by a
COMMA.

Let me be more specific. Assume that we have a file under
/tmp/test.txt with the following contents.

aaa, 10, test1
bbb, 20, test2
ccc, 30, test3
ddd, 40, test4

I want to create a 2 dimensional array with each line being an array.

lines = `cat /tmp/test.txt` will create a single dimensional array by default.

Thanks,
