parameter to another function

Question

I try the following code but when I add the bold row it fails

:Is_Error_file_empty
for /f "tokens=1,3" %%x in (%TMPLog%) do (
    if "%%x"=="ERROR" SET err=TRUE(
    **call :a %1**
)

:a
if %1 neq "c" (
    echo echo ERROR: you had an error with copying files,please see in error.log for details.
)

Answer 1

The syntax at all have some issues The parenthesis are not balanced and placed at the wrong place.
Perhaps you want to use %1 in call :a %1 but I can't see where it comes from.
Perhaps you want to use the second token? EXIT/b should be placed after a code block, else also the following code would be executed.

This code could be a base for further testings.

:Is_Error_file_empty
for /f "tokens=1,3" %%x in (%TMPLog%) do (
    if "%%x"=="ERROR" (
        SET err=TRUE
        call :errorInfo %%y
    )
)
exit /b

:errorInfo
if "%1" neq "c" (
    echo echo ERROR: you had an error with copying files,please see in error.log for details.
)
exit /b
