umask
mask = umask ([newmask])
 
This function sets the process's file creation mask to newmask and returns the previous value of the mask. newmask will affect all files created subsequently by Arbortext Editor, and will be inherited by any processes it spawns. If newmask is omitted, umask just returns the current mask.
