well, tried this right away..
touch noway
chmod 444  noway
ls >> noway
    this worked so...

but leaving a vi-session with :wq! gives me:
"noway"
E504: "noway" is read-only (cannot override: "W" in 'cpoptions')
Press ENTER or type command to continue

some phooney vi* option I dont know might do the trick?
what does " "W" in 'cpoptions' " wants me to point out?


/rmd
