Notes/Equations

The echo function is used to echo a string argument to the terminal and returns it as a value. It can specifically be used to echo System Environment variables such as HOME, TMP, HPEESOF_DIR, etc. The returned string text can then be printed in the data display. This function is similar to the Operating System echo function.
