These are the routines for manipulating the editor data bases. They live in ../s7/libX.a The program "Ttyn.c" is actually made by the program "makeTtyn" in ../s6... it produces a hashed version of "ttyn" called "Ttyn" which is useful because it runs much faster... it is however dependent on the structure of your /dev/. If you want the editor and ashell to start faster you can have them call a version of Ttyn which you can make using the program makeTtyn for your system.
