All… Does anyone know how to turn off the echo from an AREXX script ? For example: user enters a password but it cannot be seen on screen. AREXX doesn't seem to have a command for turning the echo off, nor does it seem to have commands to change screen colors. Does anyone know what memory poking can be done to change the input color to the background color (this would be an effective way to type an invisible password). — from within an AREXX script ? Thanks. Frank.
