Re: FOR loop limit

I learned something new today.

Take the following program:

D x S 3P 0
D y S 3P 0

/free

*INLR = *On;
Y = 999;

For X = 1 To Y By 1;
EndFor;

Return;

/end-free



'twas ever thus. Works that way in Fortran, PL/I, and
Pascal (off the top of my head), too. When the loop
ends, X = Y + 1, and needs to be sized accordingly.

Sometimes it helps to know a little bit about what
the compiler generated code looks like.
