Depends on the criteria for judging it a "valid ticket number" (what the 
original poster was asking for)

If there are a relatively small number of ticket numbers that are valid, 
then I'd make it a drop-down selection box (<select> and <option> tags in 
HTML) so there wouldn't be any chance of typing one that's invalid.

If not, you could have JavaScript send the form data in a manner similar 
to the way CHECK(ER) works, but it would be able to signal to the program 
the difference between a "field exit" and "enter" (unlike 5250.)

Obviously with a full blown GUI, you could query a database immediately 
when the user exited, which would be better yet.
