Re: Subprocedure Question

Joel,

One benefit is the elimination of the file fields as global variables.  They
are now in a separate  module and you have to access them through some sort
of procedure.  It becomes more obvious when you use those variables and you
gain more control over their access.  If you have two files sharing the same
field names then you no longer have conflicts where a file read on one file
inadvertently updates the same field in the other file.  Another example is
an address.  I could create a procedure to set/get the address as a whole.
This prevents anyone from updating the city without also updating the street
address.  However, if the file I/O procedures are written to just return the
entire record from the file then, yes, there isn't much benefit.
