RE: CONST vs. VALUE

[Scott Mildenberger <Smildenber@xxxxxxxxxxxx>]

Brad,

CONST means that the procedure you are calling is not allowed to change the
parameter.  I'm not sure if this should be specified when calling system
functions or not.  If the procedure is one you have written then you will
get a compile time error if you attempt to change a parm that is defined as
CONST.  I prefer to define my parms as CONST instead of VALUE so the
compiler will tell me if I'm trying to change one.
