This is worth doing because "you never know."  You might find that data
area's are passť, and you want to switch to a control file.  You might find
a mis-spelt data area name someplace.  You might find that you need to
change the size/type of the data area.  You might need to add some sort of
error-recovery.  You may have to add a default value or implement
application-security.  You just never know.  Imagine having to make any of
these changes in a dozen places in a hundred programs as opposed to one
single spot.

Make it a procedure and you have more options than inline code.  More
options = more maintainable.

My apologies for the philosophical ranting.
