This script takes a file with numbers in the format of one column. Output is file 'res-*' which gives a STATISTICAL DISTRIBUTION of the numbers from the original file with size of 'bin' delta = 1% (division by 100 ) of the bandwidth of values (i.e. difference between the highest and the lowest value in the set of numbers in the original file).
