[SOLVED] Simple batch file fails with TCC/LE

Simple batch file fails with TCC/LE

I found a problem with some batch files not written by me when executed in TCC/LE, while the same ones run flawlessly with CMD.EXE (Windows XP up to Windows 11 versions). Maybe the problem is very silly, but I can't spot it, even if I localized it to a handful of lines:

for /F %%i in (list.txt) do (
  echo ----- Process 1: %%i
  if errorlevel 1 goto Error
  echo ----- Process 2: %%i
  if errorlevel 1 goto Error
  echo ----- End with %%i
  )
goto End
:Error
echo Error!
:End

With TCC/LE version 6.3.22621 it never gets to "Process 2" text, while with CMD it executes the whole loop.

The text file list.txt contains in my sample just

abc
def

The culprit seems to be the "if errorlevel..." line, which breaks the loop before the end (though not going to the Error label).

Can anyone help me?

Here's the transcript with both command line interfaces:

[C:\Test]ver /r

for /F %%i in (list.txt) do ( echo ----- Process 1: %%i & if errorlevel 1 goto Error & echo ----- Process 2: %%i & if errorlevel 1 goto Error & echo ----- End with %%i )
----- Process 1: abc
----- Process 1: def
goto End

Solution

Well, I managed to resolve it, quite unexpectedly...

As documented on JPSoftware FAQ on IF commands

at some time in the past CMD.EXE introduced a bug on IF commands, and the Microsoft batch files were using that bug to work (...) so they introduced an option to be "buggy as CMD".

That option can be disabled from the TCC option window, called with OPTION from the command line and disabling the duplication of CMD bugs... that eventually have been fixed in the recent command processors, as even CMD.EXE works "without bugs" on IF!
