• This crashes sbbs horribly

    From elm@VERT to Digital Man on Thu Nov 3 06:25:29 2011
    I am building off the example code for the MAIL_SEND function that is located at http://www.synchro.net/docs/baja.html#Logic/Control%20Flow%20Functions.

    What I want to do is abort the mail send request if enter is pressed at the "Send mail to who? " prompt. By default, using the example code, if you press enter you will start to cycle through all the users.

    So I thought I would check for a string length of zero and then if false, continue on to the MAIL_SEND function and if true, abort. ...but this does not work. What I have added crashes sbbs when the mail_send function is called. I do enter a correct username at the "Send mail to who? " prompt.

    cmdkey S
    cls
    print "Send mail to who? "
    str name
    int namelength
    getname name 25
    strlen namelength name
    compare namelength 0
    if_false
    mail_send
    else
    print "Send aborted.\n"
    pause
    end_if
    end_cmd

    Thanks, I'll have to try that out and see if I can repro and fix it. What version are you running?

    Oh, okay. That's been fixed then. It's actually not a crash, but an assertion (not the same thing). If you run the release build instead of a debug build, do
    you have the same problem (you shouldn't)?
