Fun with Navision

Hi, can someone tell me about ETX and STX files. I can change the error messages in these files and if someone working on navision and make some error he gets funny messages, that’s fine but now i want that as we type ‘T’ or TODAY we get today’s day so if i type “Tomorrow” then it should give tomorrow’s date automatically and if i type yesterday it should give yesterday’s date. i think it can be done , any idea how

Ajay, That code is actually in codeunit 1. I have played around a bit with Y for yesterday and W+2, etc.
