Re: Postfixed characters ( was RPG, open source, and the web)

I believe what I am reading is that there is a group who prefers their code to be, as much as possible, arranged so that commenting a line does not require messing with adjacent lines. I see that as being a sort of personal insurance that debugging and later code changes won't introduce unexpected errors, either when commenting code or when uncommenting code.

Sounds good to me.

Um...I'm not sure what you're getting at...

In your example of 'minddebugging' you gave these two examples:

promptPrintForms(
rbcnppfUSER :
rbcnppfSSN :
rbcnppfSTDCD :
rbcnppfPKG
rbcnppfID :
rbcnppfTXNO :
rbcnppfHCOR :
rbcnppfRESULT :
rbcnppfDO_ALL )
-or-
promptPrintForms
( rbcnppfUSER
: rbcnppfSSN
: rbcnppfSTDCD
rbcnppfPKG
: rbcnppfID
: rbcnppfTXNO
: rbcnppfHCOR
: rbcnppfRESULT
: rbcnppfDO_ALL
)

Obviously the second example here is easier to spot that you're missing a
colon between two parameters, but that's partly a formatting issue, so lets
reformat the text in Courier New and adjust the spacing like I'd do my code:

promptPrintForms(
rbcnppfUSER :
rbcnppfSSN :
rbcnppfSTDCD :
rbcnppfPKG
rbcnppfID :
rbcnppfTXNO :
rbcnppfHCOR :
rbcnppfRESULT :
rbcnppfDO_ALL );

-or-

promptPrintForms
( rbcnppfUSER
: rbcnppfSSN
: rbcnppfSTDCD
rbcnppfPKG
: rbcnppfID
: rbcnppfTXNO
: rbcnppfHCOR
: rbcnppfRESULT
: rbcnppfDO_ALL
)


I admit that yours is easier to spot, but honestly, not a lot (as far as *
I'm* concerned) - I look for missing 'right' colons, and you look for
missing 'left' colons. But as I said, it's about what you're used to - if I
had to read your style of code, I'd be forever 'uncomfortable' - it just
doesn't look right to me. Besides which, either your IDE of choice (unless
you're just using SEU) or the compiler would throw an error here anyway...

Rory,

the quich answer is how many lines in your mail started with a "t" and how
many
ended with a "t"? and how much braincapacity did you use to figure it out

Henrik,

Mihael, you may think I'm crazy bringing in LEAN psycologist into
programming, but just notise the "commas"
that is set in the front instead of the back in the above code - the

human

brain processes these commas in a
rate 3 times faster than if it was in the end of the statement if the

code

is hirachical structured - in 10 statements
you cannot hardly measure the diffence - but programmers during years

has to

read million of statements and suddenly
the time to mind- mapp code makes a difference.

Is there a peer-reviewed study which says that we process these commas 3
times faster? Because in the absence of one, I'd have to disagree with
Barbara (gasp!) and say that I *don't* see intellectually that they are
better. Except in Dennis's great example.

Obviously we all read millions of lines of code in our lifetime, but it's
also true that, as long as we're reading code which conforms to our
preference (whether because it's a 'shop standard' or whatever), then it
doesn't really make any difference - if I am used to e.g. colons at the

end

of a line, as in my original example, and all the code I read uses that
system, then there's really no problem. The problem only occurs if we

have

to swap between different coding styles - at which point, whether we

prefix

or suffix our commas is of minimal importance compared with e.g. whether
the
code is upper-, lower- or mixed-case, whether consistent indentation is
used, whether standardized variable names are used etc.....

But

brrrrrr, make them go away.
