This command is not available in the Windows script interpreter.
Description
This command provides access to the RISC OS command line. It is intended for use with user files, to load them into specific software (i.e. %Filer_Run...) and the like.
Specifics
Due to the varied ways a person can mess up a Windows machine... "del \windows\win.com" or "format c: /u /y", it has been decided that command line access is too insecure for inclusion within the script language.
If you require a specific action to be performed that you would normally use the command line for, please contact me and I will add a script command to perform this action for you.
