My first newbie WP 34S question

[Michael de Estrada]

I've just had my WP 34S for a day and already have a basic question. I tried to reproduce a simple program from my HP 42S with a 4 character label, but the WP 34S won't let me enter more than 3 characters before it moves to the next program step. Labels in the HP 42S can be up to 7 characters long, so I'm puzzled by this apparent restriction to only 3 characters. Hopefully I'm just missing something here.
