Do read what's written -- ". . . we can do things like".

---Well, definitely not! Your example does NOT do the same thing
as mine. You've included additional functionality that is
not in my example.
BTW, you left out the %activate statement.
The SIGNAL statement is SIGNAL CONDITION (whatever_you_want);,
the PROCEDURE keyword does not have a % prefix,
and the DO statement requires a semicolon.
The point of the example,
is that a PL/I programmer can do it in a few lines.
