after many years I need to understand why in dbenham's expansion tests there are no problems, while those of aacini show a degradation.

Do you know if it is possible to handle mouse input in the dos window?

I have made further progress. I calculated the maximum expansion of the tabs and brought the tab_iter into the main loop. No more while..do / repeat..until loops I have minimized the Sets and the calls to the strlen. I have added comments doubled the size of the txt, now it's 646KB. Execution time d...

there was a wrong version in the zip I corrected and redid the tests. last version 10X short code Elapsed 83 sec. long code Elapsed 95 sec. einstein code Elapsed 44 sec. einstein code 2 Elapsed 15 sec. long code (einstein latest) Elapsed 11 sec. long code (einstein latest 2) Elapsed 9 sec. long code...

It doesn't improve the performance in my tests.
Typical result:

Code: Select all

19:39:18,23
short code
19:39:22,16
long code
19:39:29,44
einstein code
19:39:31,02
einstein code 2

I understand why
you were using an old version

there is a very strange thing, you can check that you have more experience. if I transform the tab_iter into this: set i=0 For /L %%. in (1,1,1250) do ( if !i! lss !len! ( set /a "nxt=!i!+1" for %%I in (!i!) do ( if "!ln:~%%I,1!"=="%tab%" ( set /a "d=0-(%%I %% tabWidth)+tabWidth, e=nxt, nxt+=d-1, l...

on my pc going down from 250 cycles to 100 cycles in the tab_iter procedure still increases performance by 10%

you send me a zip of your tests so that there are no errors and I do the test on my pc and we compare the times

This version on my system passed from 43sec to 11sec (4X)

I have insert the subs inline and changed the strlen into macro faster version

try this

I found that the multiple outputs within the loop including the "set /P" and file size readings were the cause of the slowdown (non-linear). I calculated the positions (making pads of the strings) and moved to a single output and removed the query of the file size and the performance doubled . Howev...
