From: Martin on 2 Feb 2010 06:40 To save having to run tests what is the quickest way of finding a string in a string? Thanks Martin
From: Martin on 2 Feb 2010 07:09 Decided to test it AT() then $ and InStr, followed by an array version AT() 3x quicker than $, $ 2x quicker than Ascan version "Martin" <spam(a)spam.spam> wrote in message news:caU9n.117601$ni7.1103(a)newsfe24.ams2... > To save having to run tests what is the quickest way of finding a string > in a string? > > Thanks > > Martin >
From: Johan Nel on 2 Feb 2010 07:10 Martin, In principle from slowest to quickest: 1. "abc" $ sMyString 2. At("abc", sMyString) > 0 3. Rat("abc", sMyString > 0 4. InStr("abc", sMyString) So in short, InStr() is the fastest. HTH, Johan Nel Pretoria, South Africa.

From: Martin on 2 Feb 2010 07:47 I found InStr slower than At() Very odd "Johan Nel" <johan.nel(a)xsinet.co.za> wrote in message news:91a73506-8dd4-4ddc-ba74-08b449e22cd6(a)z26g2000yqm.googlegroups.com...

From: Willie Moore on 2 Feb 2010 08:14 Martin, If you want more speed, use at2 or at3. They are the strongly typed versions of at.
