I heard it was 150 or 500 or something. I got the trial last week, love it!! I made about 5 or six programs and they are not huge( mabye 20 to 40 lines each). I tried to put in an M30 command, because I was at the end of writing a program, and it wouldn't save that command. I wondered if The trial was running out. If I buy the whole version, do I have to wipe the trial download off first? Thank you for helping me. I really appreciate you fine folks. Take care!
