DESCRIPTION
This commands lets you control which categories of the SAC input and output stream is to be echoed to the terminal or screen. There are three categories of output: error messages, warning messages, and output messages. There are three categories of input: commands typed at the terminal, commands executed from a macro, and "processed" commands. A processed command is one in which all macro arguments, blackboard variables, header variables, and inline functions have been evaluated. You can control the echoing of these categories individually. When you type a command at your terminal, the operating system normally echos each character. Thus the commands echoing option is of limited use for interactive sessions. The macro and processed options are useful when debugging a macro.
