I had this mistype in my program, and was wondering why the blitz debugger never picks it up (debugging on and off).res=a=hi() ;the problem part Function hi() Return 1 End Function print res print a waitkey() end in fact, it won't even catch it if the line is simply res=a=5 or any other constant. Is this supposed to happen? If it is, shouldn't res also be assigned to the value? |

(a=b) is a logical expression, like (a>b). It evaluates to True or False. So res=a=hi(i), which is the same as res = (a=hi()), assigns either True or False to res. It doesn't assign anything to a, it just makes a comparison. Note that True is the constant value 1, and False is 0. |

That's annoying....I guess I am used to python-it assigns to both. Sorry about the false bug. |
