Thanks for your response. I apologize for not being clearer. I have a three-column file that describes a bunch of parameters: TYPE1 NAME1 VALUE1 TYPE 1 NAME2 VALUE2 .... The first two are identifying strings that never change values. The values are floating numbers. This file is read in by an external program that does some parameter dependent crunching. For each iteration, while I only vary the values I write the whole file. My thought was that if I could some how tie the array of values to the file column, I could both avoid opening and closing the file and perhaps shave off a bit of time. I'll give File::Slurp a try with some benchmarking. Thanks.
