When reading a script the GTBUF default is to echo the prompt and the response read. This is very useful as it allows you to watch the effect the script is having your current program. However, in certain cases it is useful to suppress this information. This can be done with the %Echo%OFF command. For example,
ONE ! This line will be echoed %E%OFF ! This line will not be echoed TWO ! No echo %E%ON ! Still no echo FOUR ! This line will be echoed.
Currently %Echo% is a global command, and therefore, if you write any scripts that turn off the echo, you should also add an %E%ON line at the bottom to turn the echo back on for the next script.
