How I can make a screen dump (SCR) file from a program?
Press F3 to enter the monitor. Give the command S16384 6912. This will create a screen dump on the tape. Then enter the environment, use the option ‘Extract’ in the ‘Block’ submenu in the ‘Tape-files’ menu to extract the saved block onto a disk (check the radio button ‘Flagbyte is Extension’). This will create a file with extension .255 on the disk. Finnaly, rename this file to the desired name and give it a .SCR extension.
