Re: CONST vs. VALUE

["Joep Beckeringh" <joep@xxxxxxxxxxxxxxxxxxx>]

Brad,

One practical difference (the technical difference should be clear by now):

If you pass a parameter by value, you are free to change the variable
defined by the procedure interface (you might want to change blanks to
zeroes, double quotes, strip leading zeroes).  For a CONST parameter you
would have to copy to a local variable first.

BTW: the discussion shows that the manual is not very clear about WHY you
should use one or another.  In fact I had to read the explanation a few
times to understand the technical difference.
