× The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.
If you know of an easy to use, open source, search engine ... please contact support@midrange.com.

When you use that approach, you actually make the precompiler generate
twice the call to the fetch with a different set of variables, different
from the ones it created for the initial fetch. Not that is a bad thing,
but only a waste of resources. Of course the speed of execution is so fast
that it may not be a performance issue.

... simply move the fetch to an extra procedure readSomething

to enhance this approach:
let the procedure readSomething return true if the fetch was succesfull and false at EOF
move all stuff to process a record to a procedure doSomething
and your code will look like:

dow readSomething;
