Calculate delay time based on array values

I'm trying to calculate a delay time based on the values in an array. For example, tokens have been batched with a mixed item type. To calculate the delay time for the batch, it would be A*X+B*Y+C where A, B, and C are constants and X and Y are the quantities of each item type. I believe the only way to accomplish this (after reading help questions for over a day on this topic) is with custom script (which is above my skill level). Is there any other way to calculate delay time based on values in a token label array?

You should be able to do it in an expression if the array lengths are fixed.

So if the mix of x and y is in an array called mix and you have global variables A,B and C the time would be:

A*mix[1]+B*mix[2]+C

If you need to, instead of 1 and 2 as indices, use "X" and "Y" then you could set up a map and then it's just:

A*mixmap["X"]+B*mixmap["Y"]+C

Setting up a map would involve scripting though, so another way would do be to define NUMX as 1 and NUMY as 2 as global macros:

#define NUMX 1
#define NUMY 2

and then use that in your regular array:

A*mix[NUMX]+B*mix[NUMY]+C

If the values of A,B and C were stored as labels on a processor, the processing time might then be:

current.A*mix[NUMX]+current.B*mix[NUMY]+current.C

and if the mix array is on the item that becomes:

current.A*item.mix[NUMX]+current.B*item.mix[NUMY]+current.C
