FileReader reads space-delimited text files into 2D arrays line by line.

For tab delimited files use TabFileReader. For semi-colon-delimited files use SemiColonFileReader. For comma-separated files use CSVFileReader.

    // can skip empty lines:
x ="", true).postcs;

    // can skip blank entries caused by multiple spaces:
x ="", true, true).postcs;

    // do file open/close by hand if you prefer:
f = File("", "r"); f.isOpen;
t = FileReader(f, true, true);;

    // take letter "a" as delimiter:
x ="", true, true, delimiter: $a).postcs;

// write a test file with numbers:
f = File("", "w");

x.collect(_.collect(_.interpret));    // convert to numbers.

    // or do it immediately:

// write a test file with several lines of numbers:
f = File("", "w");

(1..100).do { |n|
    f.write(n.asString ++ if (n % 10 != 0, " ",; };
