Re: Line-by-line commenting in source code

Rob,

>The if's confuse me.

Those type of lines have been known to be used by vendors to "salt" program code
to help substantiate copying of code, as it is otherwise unlikely a "clean room"
approach to performing the same process would include the same lines.  If this
is the reason it exists, that would also explain the lack of comments about its
inclusion.

I have also seen similar IF tests code with a conditioning indicator, in code
which began in RPG II on the S36.  Since it does not support *INxx, you can't
test the indicator itself with an IF statement.  So one work-around is to use a
conditioning indicator with an otherwise always true IF expression just so you
can condition a block of code on a single indicator test.
