Dear monks, I have a problem here, and I want to use perl to automate this reocurring calculation: I have files with values organized in 8 rows and 12 columns (space separated) and I want to create a new file showing the differences of the corresponding values (e.g. value row1,col1 in file1 - value row1,col1 in file2) in the same 12x8 pattern. Could you give me ideas for tackling this problem? cheers, Lorenz
