How can I turn off the printing of the command line: ? printf ... and just see the "real" output?

Apart from this, I am running some Monte Carlo simulations with gretl, and I would like to note that, although I put "set echo off" at the beginnig of my script file, there are some sentences that are being written to the screen... Thanks for the report. Since this is an issue that other people are likely to run into as well, let me explain: * "set echo off" suppresses the echoing of the commands in the script; that is, you should just see the output from those commands. * If you don't want to see status messages such as "Replaced matrix 'E'", then in addition you should do set messages off * Finally, if you want a loop to run quietly, without reporting the number of iterations completed, add the "--quiet" flag to the loop command, e.g. loop i=1..10 --quiet Perhaps there should be one global command to achieve all this, but that's how things stand at present. Allin.
