Re: RPG read loops

Hi Ali
<snip>
What would be nice is (may be already there, but I
don;tknow)%read(File) BIF, returns a boolean true (and of course the
file buffer), if the read was successfull. Then we can have a read
loop like below:

DoW  %read(FileToRead)
.....
EndDo
</snip>

You could make a sub-proc like that, that reads the file, and returns
true if it is not end of file.  In my opinion, that would hide the
details of what's really happening, as would the BIF.  Kind of like
setting up input primary, and hide the whole loop.
