Learning to program on the HP Prime (intermediate to advanced)

[tcab]

Thanks, works fine now.

Playing around a bit, it looks like MSGBOX works OK if you pass it the integer I without converting it to a string. Also, returning I might be a nice enhancement if the user wants the value on the main calculator history/stack. E.g.

PHP Code:

MSGBOX("You chose " + I);
return I; 


I know it's a toy program, but this information might help the original poster.
