i mean in logo TD i showed a text message then i want to show next text message bellow previous text message ?

CONSIDER FIRST TEXT MESSAGE IS

DARIN DOWN 1

THEN NEXT TEXT MESSAGE SHOULD SHOW BELLOW THIS MESSAGE

DRAIN DOWN 1

VALVE IS FAULTY

thanks for you help but my task is more complicated

the first line is the step name like this

DRAIN DOWN 1

then second line should change based on 3 situation :

1-DRAIN VALVE IS FAULTY

2-INPUT OR OUTPUT VALVE IS FAUTY

3 REM. TIME OF A TIMER

there is a way?

Thats not possible......

Exept if you make a lot of TEXT messages, for all possybilitys and use them by OR and AND blocks
