The compiler doesn't want you to close the files in all the functions,
it's just suspicious if it doesn't find a CLOSE in *any* function.  Since
there's no way for files to get closed in a NOMAIN module other than with
a CLOSE operation, the compiler thinks you might have forgotten to code a
CLOSE for the file (well, it's really me who thinks it; I put that warning
message in the compiler).

If you might want to close the files at some point in your application,
code a "cleanup" function that does a CLOSE *ALL (and UNLOCK *DTAARA
if you keep data areas locked).
