and I was not offering one to Mr Pace but to others here who may prefer logic
to sloganeering.
The relational expressions a > b and b < a are equivalent; and either can be
obtained from the other by simple, readily learned transformations. In
particular, (4,>,RC) can be derived mechanically from (RC,<,4). It has been my
experience as a teacher that people who have difficulties with JCL and related
programming difficulties do not know enough formal logic asnd lack manipulative
facility in it. Both can be and should be taught, except perhaps to Mr Pace,
who prefers shibboleths.
He of course has a right to his views, which he has exercised in setting them
out here; and I equally have a right to dispute them when, as here, I judge
them to be nonsense.
