Commands can be run directly using the command line of ndashell or script files.
Script files are normal text files containing one command per line.
A script file can be run directly by writing its name on the command line. That is, all characters between two backslashes will be taken literally in the first evaluation of the command line. Some commands, such as if and while , re-evaluate the specified command line before executing it. Error messages are displayed regardless of the echo setting. Most of the other command also produce an error message, if they are given unexpected switches or illegal data types.
