I was wondering, is there some sort of YES: device on the amiga that does something that the yes command would do on unix? Simply put, openning a file "YES:yes" for reading would make the reader read a bunch of "yes" or (yes:no a bunch of "no"s) Why would I want this? Well, sometimes, when I am unzooing or unlharcing I come up with a: zoo file exits Replace? (Yes/No/All/Quit) and often I would like to say NO for ALL of the existing files (Not one of the options in that small menu) And having a YES: device that does that would do the trick. Now, if a device like that doesnt exist, how hard would it be to write one?

You can try to obtain a simple handler, like the pipe: device and hack it. You
would remove a lot of stuff and change he handling of read packets. I think
the source for a pipe is available fish disks #55 and #84(?).

There _are_ options to suppress these messages: "zoo e//O" unpacks an archive with complete directory tree and without asking questions and without overwriting files "lharc -m e" does it too. (for .lzh-files) Writing a device would be a bit of work. What about using pipes? I'm using ARP and the conman-handler to get real (unnamed) pipes. The yes-program: main(argc,argv) int argc; char *argv[]; { if(argc==1) while(1) printf("y\n"); else while(1) printf("%s\n",argv[1]); } Your command would then look like yes n | zoo e// Jochen Erwied | (inside Germany) mack@wizard.ruhr.de Emil-Figge-Str. 3/005 | erwied%wastl@laura.informatik.uni-dortmund.de W-4600 Dortmund 1, FRG | +49-231-750331 (data) +49-231-756081 (voice) -----------------------+ "I'm not a number, I'm a FREE man" - "hahaha..."

Doing: Copy "chars:This is my string*N" ram:x would put "This is my string" and a terminating newline into the file ram:x. Adding a flag (Where?) to wrap around when you got to the end would solve your problem. <mike -- Tried to amend my carnivorous habits Mike Meyer Made it nearly seventy days mwm@pa.dec.com Loosing weight without speed decwrl!mwm Eatin' sunflower seeds
