Re: RPG read loops

[antoine.contal@xxxxxxx]

Paul,

I think Ward Cunnigham's wiki has a good discussion about this topic.

Basically, if you have to change the read or exfmt statement, you could forget 
to change the other one.  It happened to me once or twice last year.

Regards.

Most programmers seem to code with the single read/exfmt style which IMHO
complicates the code.  In a DoU/Read loop the body of the loop is nested two
deep inside the DoU and an If statement.  In a Read/DoW/Read loop the body
of the loop is nested one deep inside a DoW.  Doesn't this reduction in the
nesting of the body of the loop improve the program?  Readability is
improved.  Performance is also improved (although minor) with the removal of
one test against the end of loop.

Other programmers I work with are adamant about not coding more than one
read statement.  Why is coding more than one read statement such a problem?
