***Ralph, I've already agreed that 'random access' ('direct' would be a 
better term) is merely a term for the particular way of organising file 
access and the syntax used (what is physically happening behind the scenes 
on the disk is anything but random (though it appears 'direct' to the 
programmer and user )). But if that way is good enough for the designers of 
vb6 then it's good enough for me!

***well 31 actually :), as it was fully described in interpreter BASIC, then 
GWBASIC, then QuickBasic, then vb6... and it's available in the dreaded 
dot.net too!  (Only there UDTs are replaced by Structures...).  But records 
can be put to and got from directly by reference to the wanted record, and 
of course the records can be searched too for required strings and so on.

On another note, since 'program' is being replaced by the shortened buzzword 
'app', does that make us all mere 'applicators"?
