Then I read the damn manual: 'P' Toggles the command prompt on and off. Unless a prompt string is specified with the command-line option '-p', the command prompt is by default turned off. The default prompt string is an asterisk ('*'). So ... if you want no prompt (in other words, a zero length prompt) in some scripted invocation of ed, just don't specify the "-p" option. Problem solved. It all works as coded, documented and standardized. -- Paul Jackson jack...@fastmail.fm
