Re: Chain vs SetLL/ReadE

[Jeff Crosby <jlcrosby@xxxxxxxxxxxxxxxx>]

Terrence,

For a set of records, I do what you do, with a slightly different Do 
statement:

SetLL (KeyFields) FileName;
DoW 1;
 ReadE (KeyFields) FileName;
 if %eof( FileName );
   leave;
 endIf;
do my stuff
EndDo;

For single record retrieval, I always use Chain.

For testing whether an record exists without retrieving it, i always use 
SetLL.

The above methods seem the most readable to me.  Readability is more 
important than nanoseconds.
