Binary items and Nulls

}' ${FILEN}
done

Its the contents of field 'value' that I want to pass to the
conversion function - but seems to have nothing in it
Thanks in advance to anyone with an idea for a fix

Change the sprinf to
[tt]
value = sprintf(&quot;%06s&quot;,substr($0,1,6))
[/tt]
Hope this helps. CaKiwi

Sorry CaKiwi - still no joy !
I may have to write a C prog to do it
Thanks anyway
