Why “The system cannot find the batch label specified” is thrown even if label exists?

Question

While running a batch file in Windows XP I have found randomly occurring error message:

The system cannot find the batch label specified name_of_label

Answer 1

I encountered a similar issue just now with a .cmd file and Windows 8. The solution was to change all line endings to CR+LF DOS style. The issue was confusing because the batch file mostly worked and rearranging lines changed the effect.

The .cmd file looked like:

call:function_A "..\..\folderA\"
call:function_B "..\..\folderB\"
call:function_C "..\..\folderC\"
call:function_D "..\..\folderD\"
goto:eof

:function_A
rem do stuff
goto:eof

...etc...

Function C would cause error "The system cannot find the batch label specified". Strangely it could go away by rearranging the calls. Changing line endings from 0x0A to 0x0D0A seems to have fixed it.

Perhaps VonC meant "the batch file must use CRLF line endings".
