Nothing critical will happen.. I will make understand with
example below:
Consider some 2 bytes as * are before that variable as $
and then rest copybook as & , so after changing table
layout will look like:
**$$$$&&&&&& and program will layout as
**$$$$$&&&&&&. So, now what happens table always passes
something as 4 bytes to 5 bytes which easily is compatible
with a bigger space. So, you will see a space actually
which might disturb your output.
