Just because I like to argue with Joe...
IBM came up with
x+=1; // add 1 to x
instead of having you do
x=x+1;
so that if you copy a bunch of code, and change x to y, you don't forget
to change x on both sides of the equation.
So, if you copy code from one area to the program;
// get customer record
chain cust# CustMast;
if not %found(CustMast);
and then post that later in the same program
// get item information
chain item# ItemMast;
if not %found(CustMast);
and forget to change the name of the file in parenthesis you'll have
"issues". Compiles fine. Most times may even work fine. Until you get
that order with no matching item number (because your database vendor has
RI phobia).
