As a stop gap measure, we are using Google's custom search engine service.

Id. One line of code and you got it. Nope, "I don't like to use
that" so
he is writing half a dozen different version of the logic using
monolith
code in each program to read the data area in character, convert it to
numeric, update the data thru data structures in global memory and
then
move it back and then update the field rather than use the one line of
code.
I consider that a "standards" issue. "I don't like to use that" is
NOT an acceptable excuse. Code reuse has a higher priority than likes
and dislikes. If he worked for me he'd use the pre-existing function
or he'd be looking for another job. Cloning code into multiple
programs is unacceptable because it increases maintenance.
What annoys me the most is one should not have to EXPLAIN this stuff.
It should be standard practice for programmer's and once something
like this is pointed out they should WANT to use it.
Why do so many shops seem to tolerate people with this attitude? Why
keep the dead wood around? If they don't want to move forward then
get rid of them so they don't hold others back.
Even tried to show him how you could define the data area in "D" specs
and define the field as a zoned field right in the data structure
so you
don't even have to mess with it. Nope, I prefer to define data
structures in global memory, move stuff into it, do the operation and
move it back out.
Ask him WHY? Get him to explain the advantages of his technique over
the other more elegant technique. "I prefer" is not good enough
unless there is really no documentation, coding, or performance
advantage of one method over another.
This is another example of "Get the data structures right and the
code falls into place". A slightly more complex data structure
results in less executable code to maintain.
