In fact, Ed might need to do something of the sort inside his
code in order to ease the transition to 1.8.  Perhaps an SPLEVEL
check.

But I wonder why he placed his private definition of S99RBXLN
in each of several source files rather than in a macro.

Hmmm.  Ed used S99RBXLN rather than the more obvious S99RBLEN
to minimize the likelihood of collision with a possible IBM
update.  And IBM S99RBXLN rather than the more obvious S99RBLEN
to minimize the likelihood of collision with possible private
customer circumventions.  Poker strategy?  Rock-Scissors-Paper?
Prisoner's Dilemma?
