Batch Script "Timeout" Error: Invalid Syntax. Default option is not allowed more than 1 time

Question

First off, I'm using Windows 7 64-bit, if it makes a difference. I have a batch file in which I'm using the "timeout" function, written as such:

*code does some things*
timeout /t 100 rem wait for 100 seconds for the above thing to finish

If I do timeout /t 100 in the command line, it waits for 100 seconds as I would expect. However, in the script it gives me the error:

ERROR: Invalid syntax. Default option is not allowed more than '1' time(s).
Type "TIMEOUT /?" for usage.

The instructions for timeout are /t for number of seconds to wait, /nobreak to ignore keypresses, and /? to display the help message. I'm not sure what syntactical error I'm having, or what "default option is not allowed", especially since it seems to work perfectly fine outside of the batch file.

Answer 1

rem wait for 100 seconds for the above thing to finish
timeout /t 100

You cant's set a comment on the same line as the command.

Answer 2

A comment is another command. So if you want it on the same line you need to use the & like this.

timeout /t 100 & rem wait for 100 seconds for the above thing to finish
