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)?
