This will read the entire file.
If you think you know what to do if the file is in a variable and
the file is not huge, then you can also use the URL keyword to
bring in the entire file at once.
Suppose you don't read it in all at once. How you proceed depends
a lot on how your file is structured. You might be able to get by
with something like this:
repeat ...
read from file "Foy.db" until foyDbRecordEnd
check result for eof, worry about partial and break out of loop
translate record into a form to put into field
put that into field
end repeat
In general a lot depends on the file format.
Is it ascii or binary?
What is a record?
Is a single line? (See TD on linefeed on end-of-line.)
Multiple lines? What separates them?
Fixed length or variable length?
et c.
In Revolution, you can bring in a file that is in an arbitrary file
format. Some will take more work than others.
