Re: %EOF with READC

[Jerry Adams <jerry@xxxxxxxxxxxxxxx>]

Bob,

Consider me kicked.  The manual, in fact, omits the file name in the 
code example.  I prefer, though, including the file name here  and 
%found(), etc., simply for clarity and, in this case, consistency (the 
READC is, after all, the preceding op; not like it's buried somewhere 
else in the code).  Just one of my (many) idiosyncrasies.
