In the Command Window type help dos or doc dos. The dos function executes a DOS command and returns the result:

status = dos(command) executes the specified DOS command for Windows® platforms, and waits for the command to finish execution before returning the exit status to the status variable

The command string in this case is rm *.ascii which should remove all files with the ascii extension from the current directory.

I should have indicated that I ran this piece of code on my Mac where the rm command is valid and so will (and did!) remove all files with the ascii extension...

rm is a Unix command: https://en.wikipedia.org/wiki/Rm_%28Unix%29 not a DOS command.

Does that command even work, or does it throw an error?

For DOS, use del instead of rm. Or use the system() function instead of the dos() function.

I am getting this warning.

'rm' is not recognized as an internal or external command, operable program or batch file

[Image Analyst]

Yeah, because it's not a DOS command. Try using del instead of rm if you want to run it.

ok. thanks
