Here is an example of
what I'd like to do:
c eval Duty = CanadianDuty(parm1: parm2: parm3)
and the procedure CanadianDuty would have 3 parameters as input and
return the value of the duty.
I believe I can do that process, but I *know* I have no idea how to do
the same thing where I need to return 2 values, say "Duty" and
"Tariff".
One way to do it is to return a data structure, so your code would look
like:
c eval CustomsFees = CanadianDuty(parm1: parm2: parm3)
...
c eval totalCost = ... + CustomsFees.duty +
CustomsFees.tariff ...
You can also use "output" parameters, as you might if you were coding a
program instead of a procedure to retrieve the information:
c callp CanadianDuty(parm1: parm2: parm3: duty :
tariff)
Yet another way would be have one procedure for each type of fee, which
would be closer to your first example:
c eval Duty = CanadianDuty(parm1: parm2: parm3)
c eval Tariff = CanadianTariff(parm1: parm2: parm3)
