My limited programming knowledge is so old that this will take me hours, but I know some of you here could do it in 5 mins. I need to prompt for a file to read in, (a comma delimited text file), calculate an additional column, and prompt to write back to a new file. I know it is probably a matter of reading the file into an array, calculating and adding the extra column with a do-loop, then outpiutting it, but I've forgotten how. I also don't have any programming languages currently installed. The input file is like this: 1,"35000/001",1/1/2002,06:00:00 2,"35000/001",5/2/2003,07:00:00 3,"35000/001",6/1/2004,07:00:00 4,"35000/002",3/9/1999,05:32:00 5,"35000/002",5/4/2004,04:34:00 6,"35000/003",4/1/2003,07:12:00 7,"35000/004",5/5/2001,12:34:00 8,"35000/004",3/2/2002,17:30:00 9,"35000/005",9/7/2004,12:32:00 and the output file would be 1,"35000/001",1/1/2002,06:00:00,1 2,"35000/001",5/2/2003,07:00:00,2 3,"35000/001",6/1/2004,07:00:00,3 4,"35000/002",3/9/1999,05:32:00,1 5,"35000/002",5/4/2004,04:34:00,2 6,"35000/003",4/1/2003,07:12:00,1 7,"35000/004",5/5/2001,12:34:00,1 8,"35000/004",3/2/2002,17:30:00,2 9,"35000/005",9/7/2004,12:32:00,1 The new last column is basically a counter, which is re-set upon a changed value in the second column. I know it is asking a lot, but I'd be really grateful if someone could give me some assistance on this many thanks Ray
