I'm not sure I follow. I would normally only use CALL_FUNCTION once,
and decide on the function string to use at run-time. If you mean you
still have to select which function to use, well, yes, that's true,
but we are really only talking about a few lines of code here, right?

The other option is to code one function with many different cost
functions inside, and then select it using a keyword, as in:

function my_cost_function, ..., method=string

case strupcase(string) of
'MEMB': value = ...
'LB' : value = ...
'SR' : value = ...
end

return, value
end

This allows you to only have one file with many different functions.

You could do something similar with objects as well I guess.

Good luck,
Craig
