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...
