Irene,

If you use chrtran() to remove characters you can see that the code is running O(n²) which is unsatisfactory for large values of n. strtran() does not suffer from the same flaw:

StrToFile(strtran(FileToStr('c:\tmp\wtbsold.txt'),'"',''),'c:\tmp\wtbsold.txt')

There is a DeQuote() function over on my website that performs even faster that strtran. It's under Samples.


>I'm using these commands to get rid of the double quotes in a text flat file. The code works accept when the file contains more than +/- 2000 records (lines) the vfox session hangs (NOT RESPONDING). Is there a limit or do I need to include in my code a command that tells vfox to wait until the FileToStr command is done? Please help...
