whats the problem in the coding

My program does not write a sorted output to the output file.
Can you please let me know why?
Please select a file where the data to be sorted is entered and another file where the sorted data must be stored.

It's not clear to me what you're trying to sort. Is it each line in a file? If yes, then you need to put each line into a separate array element. The way you're doing it now, the entire file content is a single element. If you want to sort a single line by characters, you have to do the same thing - put each character in it's own array element. If you would attach a sample text file with more details, it would help a lot.

Because the net result of your vi is to merely capitalize everything you are reading in. Everything after the capitalization cancels itself out (like saying 2+3+5+6-6-5-3 = 2). When you read in the file, it's taken in as 1 long string. With no parsing of the string to array elements based on space, CR, LF, etc. it's just 1 long string. If I'm correct in my thinking of what you're trying to do, you should read in the file as a spreadsheet string with whatever separator is appropriate.

If you place probes or indicators all along the data flow, you'll see what's happening.

Dave.

Thanks for the response. I want every element to get into an array element so that i get a sorted output.
Enclosed is a sample text I would like to sort.

I modified your code for sorting. You can use probes and indicators to see how it works.
