What steps will reproduce the problem if we use new ;; command then we get Error 27: Unrecognised command

echo fred ;; # this is a comment pause

if we had a REM command we could have

echo fred ;; REM this is a comment REM This line is ignored too

and we would not get any error message as REM would be a valid command

Please provide any additional information below.

Strangely, we get no error messages if we add another valid command

echo fred ;; # this is a comment ;; is64bit pause

seems current does not support comment in commandline.(only in menu)

because in commandLine This is not necessary.

in batch you can comment out a line using "#" or "::"

I am not sure what you mean? The following menu shows an error

title fred echo fred ;; # this is a comment pause

Try this ..

title fred echo fred ;; # this is a comment pause

This now works as expected

Thanks :-)

Thanks too..
