RE: explicit close

[Scott Mildenberger <Smildenber@xxxxxxxxxxxx>]

Buck,

        I know your response said typical I/O functions but what is your
opinion on functions such as GetCustName or ValidStation that aren't
obviously doing any I/O?  The user of the function doesn't really know if
files are open/closed (nor should they care).  I tend to take the approach
that the files used in a service program are USROPN and they are opened by
the first procedure that uses them.  I usually just leave the file open
unless it is a file/procedure that isn't typically used very often.  I know
this can leave a number of files open in interactive jobs but I haven't
noticed any problems with this, although that doesn't mean there aren't any.
Thoughts anyone.
