To test on an XP system or higher, copy the following files in the dedicated folder described in the second post of this thread ("strLen_tests_stub.txt", "strLenA_loopUnrolled.txt", "strLenJ_20101116.txt" and "strLenL_dipstick.txt" should already be present to...

(tests' sources in the next post) (Using «,1» alleviates the need to worry about the command line limit. One less thing to think about ? No impact on speed !? I like !) Wow, astute ! 'strLenN_binarySplit' (.txt) manages to complete in a good 90% of the time taken by the yet already refined 'strLenL_...

Ooops, apparently the word 'gauge' is a false friend ; it appears that I should have used the word 'dipstick' to convey what I had in mind ; I've corrected it in the preceding posts. (By the way, I know of no preexisting name for the technique you employed and it reminds me of when one has to gauge...

To test on an XP system or higher, copy the following files in the dedicated folder described in the second post of this thread ("strLen_tests_stub.txt" and "strLenI_chunks.txt" should be present too). Note : the differences in the amounts of comments of each function do have a n...

As in : your use of a 'dipstick' completes in less than 66% of the time taken by a binary search . @DosItHelp : Compared to the version with some splitting, the 20101116 version of «:strLen» completes in less than 90% of the time for s...

WSH is cool too . That said, there is some hefty overlap between what batch and WSH scripting are fit for. Obviously, when comes the time to measure the length of a string, WSH has the upper hand. There are many reasons - objective/subjective/good/bad - though, to use batch rather than WSH (even in ...

To test on a system of the NT line, copy the following files in a dedicated folder. The first file is intended to be modified at will depending on what is tested. The others will/should require no tweaking. The tests of correctness produce results in {OK,FAIL}. After a comprehensive test of correctn...

Hi ! I was wondering how to retrieve the length of a string ; I've seen «:strLen» (http://www.dostips.com/DtCodeCmdLib.php#Function.strLen) ; yay ! I've also managed to improve it, at least on this configuration : Intel Core Duo T2300 1.66GHz / Windows XPSP3 {5.1.2600}. The code is towards the end o...
