Batch file interpretation needed :-) 1

[sqlsadie108]

Hi, just trying to "quickly" figure out what this batch file is doing... I think it's putting a time stamp on some files, but I don't get the "FOR %%A IN (0 1 2 3 4 5 6 7 8 9)" part.

Thanks much

REM Use ERRTIME.EXE for a sorted date (or time) in MS-DOS 7.*
ERRTIME -y > NUL
FOR %%A IN (0 1 2 3 4 5 6 7 8 9) DO IF ERRORLEVEL %%A0 SET ERR10=%%A
...

FOR is a dos command which basically does a loop through the values in the array.

What is actually being processeed by the FOR command is this.

IF ERRORLEVEL 00 SET ERR10=0
IF ERRORLEVEL 10 SET ERR10=1
IF ERRORLEVEL 20 SET ERR10=2
IF ERRORLEVEL 30 SET ERR10=3
IF ERRORLEVEL 40 SET ERR10=4
IF ERRORLEVEL 50 SET ERR10=5
IF ERRORLEVEL 60 SET ERR10=6
IF ERRORLEVEL 70 SET ERR10=7
IF ERRORLEVEL 80 SET ERR10=8
IF ERRORLEVEL 90 SET ERR10=9
