Re: Indicators -- RPG400-L

Hi Bob,

Knowing you both by reputation and from this list, I have enormous respect
for you, your expertise, and your opinions. It is with all that respect
that I humbly suggest that "readability" is in the eye of the beholder. If
you find /free more readable, then I won't argue with you. Personally, I
don't, although I hasten to add that a) I don't find it "less" readable,
either, and b) I'm very open to the possibility that I may change my
opinion in the future.

The question of readability has come up before, and I don't want to open
another can of worms. But I am firmly convinced that, in programming
languages, readability has more to do with what someone is used to and
whether the logic and program flows are clean and consistent than in how
many indents you can use. At my current job, my boss has developed a
consistent structure for his programs, and once I learned what it was I
found (and still find) it very readable (and he loves left-hand
indicators). Can someone write cryptic, confusing code using left-hand
indicators? -- sure they can, and Ron posted a great example. But I have
seen code written in "free" formats that  was convoluted and confused, and
the mere fact that it was free-form didn't help anything.

In the example I posted, I took a code sample that I thought was perfectly
clear and readable and asked, "doesn't trying to eliminate the indicators
make this worse?" You, Charles, and others have shown me that the answer
is, "not necessarily". That was good, I learned something, thank you all.

But I didn't find the examples "more" readable; instead simply "as"
readable, and that's why I don't feel any incentive to put time and effort
into switching over. Like many shops, we have a huge amound of installed
code that was written in the old way.  I _do_ see great benefits in
switching to RPGIV -- in fact, I convert just about every OPM program I
work on. I love "Eval" and the string handling functions, and I think in
general the language offers huge improvements in functionality. If all
that moving on to /free will give me is "readability", though, then right
now, for me, I don't see the benefit.  But time will tell . . . .

Respectfully,
