The order of testing in this old version of protcode.tex is wrong too
(in the previous example > 14 is never tested because > 13 is true in
that case). Here is a correct version which also does not need the >99
test (because it is included in >14):

\ifnum\pdftexversion > 14
\ifnum \expandafter\pdftexrevision > g
