Hi Sam:

There are two approaches to double-enter: 1) independently, 2) the 
second file depending on the first.  You seemingly chose the latter 
("prepare for double-entry").  If you choose that option, you must enter 
the records in the same sequence (I believe) and the value of each field 
in the second record will be compared to the corresponding one in the 
first and a discordance reported, so you can verify.  Thus, no need to 
enter twice.

Alternatively, you enter your related file pairs independently between 
first and second entry.  You must have a unique identifier in both the 
parent and the child file.  The sequence then doesn't matter of course.  
After you have entered parent1-child1 and parent2-child1, you validate 
parent1-vs-parent2 on the unique identifier, then child1-vs-child2 on 
that identifier.
