RE: READE is confusing to me

["Shaw, David" <dshaw@xxxxxxxxxxx>]

Booth,

I think your code will get stuck in the loop - %Found will always be true,
since there's only one Chain, which is before the DoW.  I imagine it can be
made to work, but my brain's off-line at the moment (after lunch, y' know?
;).  As an alternate work-around, I've got a few programs that substituted
SetLL/ReadE for the priming Chain, then just use %EOF.  I found that
limiting, too.

EndLoop provides a lot of flexibility, since I can set it for any reason I
want in the code, plus I can see what's in it while in debug.  Using the
BIFs directly is more limiting, especially two years later when someone
unfamiliar with the code (like me after that amount of time <grin>) has to
make a change to it.  Just as an example, if I want to add code for %Error
at a later time (later in the debug cycle, or later in life), it's very easy
to just insert it in the code and add another update of EndLoop, without
compromising readability at all.

I'm trying to learn this stuff.  Why not the code below, but like this?

     C     Key           Chain(E)  File
     C                   DoW         (%Found Or Not %EOF) And (Not %Error)
                 *  stuff
     C     Key           ReadE(E)  File
     C                   EndDo
