Thanks, Larry! I think I get your point. But why is the above better
than this:
setll (key1) addressFile;
reade (key1) addressFile;
dow not %eof(addressFile);
if someCriteria = true;
getGeoCode( key2: dsGeoCode: rc);
if rc = OK;
// do something with the long and lat...
endif;
endif;
reade (key1) addressFile;
enddo;
Why is the chain better than the call? The more I see this, the more I
have a problem with usurping a known opcode. Prior to this, READ/CHAIN
was getting data from a database. Now I'm not really sure what it's doing.
Anyway, enough on this particular topic. Either way works, and they're
both doing essentially the same thing. I think it really is opinion at
this point.
Joe
