If you have a session on the console, a quick & dirty way to disable input is to start an IF with a false conditional and not give the ENDIF, like: :IF !HPYEAR = 1998 THEN Cursor up two lines, erase the "IF" and "*** Expression False", and the terminal is effectively locked until someone types in "ENDIF". This can also be used to mystify your fellow employees, if they are foolish enough to leave their terminal unattended for a moment or two :) ----------------------------------------------------- Confidentiality Notice: This e-mail transmission may contain confidential or legally privileged information that is intended only for the individual or entity named in the e-mail address.
