Figure 9.9 Adding Input Parameters to a Function
In this function, you’re going to be passing in the customer requirements: what
the monster is going to be used for, how scary it needs to be, how many rages it
has to fly into each day, and so on. Based on the rules you’ll add to the function,
a result will come back saying what ingredients to use.
To enable such passing of data backwards and forwards in your new function, you
need to create the signature—that is, what data you expect in and what data you’re
returning. In regard to parameters, a BRFplus function is like a cross between a
function module and a method; the name says “function,” but the import and
export parameters can be tables, as is usually only possible in methods.
