Bug ID: 56498
           Summary: misinterpretation of the '/' character
           Product: Wine
           Version: 9.0
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: cmd
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

this sequence causes two different results on wine and windows :
(french date)

echo off
cls
echo %date%
set year=%date:~6,4%
echo %year%
pause

on windows :

29/03/2024
2024

on wine :

29/03/2024
202

wine seems to interpret / as an escape character

--- Comment #1 from Eric Pouech  ---
actually, doing
> set "d=30/03/2024"
> set year=%d:~6,4%
> echo %year%

gives the expected result

there's a off by one in the computation of the length of expansion of
variables:  the length of "magic" variables (like DATE, TIME, CD...) isn't
coherent the length of "non magic" variables

I'll send a patch later on
