Cannot step into and/or call another .bat file when debugging .bat file

I'm debugging a .bat file and there is a line like the following:


But, when I try to step into that script (F11 key) there is a message in the cmd window that says

TCC: ...\path\to\bat\file.batch_file.bat [line number] Unknown command "scrip[ts\some_other_script.bat"

Click to expand...

How do I step into another batch file? Even if I don't try to step into the batch file it still fails as above.
