So what is the difference between....

My example of a Program "PROGRAMA" having one less field defined in it
because didn't recompile it, calling "UPDATEPRO" with the New field defined
in it to do the REWRITE, READ, WRITE etc.....

OR

Having a Using just one Program using a Logical file of a Physical file to
do reads, rewrites, writes and such and I add a new field to the Physical
file but don't recompile the program?  Wouldn't that Program also have the
ability to write out Garbage because the Logical doesn't have the new field
in it yet?
