Quick question on functions

[wezelboy]

Does assigning a return value in a function immediately cause the function to return?

-P

No, you can have statements after the function's return value is assigned, or have several exit points in the function where an appropriate value is assigned.

eg. :

function abc(X, Y :Real) :Integer;
Begin
abc := 0;
if X>Y then abc := 1
else if Y>X then abc := 2
else if (X<1) or (Y<0) then abc := -1;
End;

Thanks.

I guess I have to leave the GOTOs in my function. Dijkstra would not be happy with VectorScript ;-)

[MullinRJ]

In all the years I've programmed with Pascal, I've never had to use a GOTO. If you learned to program with BASIC it may be ingrained in the way you think about programming, but it's definitely not necessary. If you want to lose the GOTO's, post more and I or someone will help you kick the habit. If they don't bother you, we won't tell Dijkstra. ;-)

i also don't use goto's because you'll need to be very carefull with them. if you have pages of code, it gets confusing and hard to find where to go. better not use them.
