PL/I has never had integers.
It always has had integers.
The arithmetic rules for scaled fixed point are different from those

Look at the second result following the program.
You will see that A/B == 4/3 yields 1.

You are looking at the wrong part of the table.
This discussion is about DECIMAL operands.
what I wrote is correct for such.
See Table 15 top entry, for ANS rules for division;
Table 16 top entry, for IBM rules.
