I have a value "00000000" without quotes where I am adding a 1 to any of the positions if a value has changed in an input file but in some cases I will end up with a value of "00130012" but what I would like my end result to be is only 0(unchanged) or 1(changed) in any position ... in other works if the value is greater then 1 I want to change it back to a 1. I'm trying to figure out if the easiest way to do this would be a replace function of some SORT? I'm thinking there would have to be something simpler then a doing a split and checking each value. Or instead of the above is there a way to check the position of a digit within the value to see if ALREADY 1, if it is don't add again. I COULD do 8 counters for each position that if greater then 0 add 1 to the position but keeping track of a bunch of counters seems like a lot of work. why don't you show us your code so far? That would save one *censored* of a lot of time asking questions. Why don't you, instead of adding 1 to a position, check if the digit in that position is already changed to 1 and if it is, leave it alone?

Ended up using counters to track if I had already added a 1 to that position. Not sure how to go about checking if the position already has a 1 within a number.

Didn't post the code as it is quite messy and very much spaghetti code. Not really sure yet how to clean it up into tidy functions but at least it works and does what I want for now. I'll still posted if you CARE to see as I'm always interested in learning a cleaner meaner approach. Quote from: nothlit on October 29, 2010, 01:30:52 PM
