RE: RPGV?

Does %DIV's result count as overloading?

"If either operand is a packed, zoned, or binary numeric value, the
result is packed numeric. If either operand is an integer numeric value,
the result is integer. Otherwise, the result is unsigned numeric. Float
numeric operands are not allowed."

I suspect that the rules that govern the operation of BIF are

closely

tied to the rules that limit our procedures' abilities.

There are existing precedents of BIFs working in an overloaded

fashion.

For example, the %DEC() BIF can take a Unicode, Alphanumeric, Date,
Time
or Timestamp field as it's first parameter. Indeed, the 2nd parameter
is different for a D/T/Z field than it would be if it were a character
string.

The same is true of the %date(), %char(), %int(), etc, etc BIFs...

they

all can take their input from just about any data type. Something we
can't really do with subprocedures.

Good point, Scott. But I was thinking more in terms of returned-type
overload. Any examples of this would be ... enlightening. :)
