RE: More functions?

I need to calculate a standard deviation on a 60 record sub-set of a
larger
table of records. Each time I perform this calculation I'll drop the
oldest
record and add the just read record and perform the calculation again
until
I've done this for all the records in the table. I was able to do this
same
type of calculation to come up with a "moving average" using XFOOT on
the
array holding the data and dividing by the number of elements in the
array.
Anyone know a simple way to do this inside RPG?

XFOOT is an RPG instruction, right? What am I missing?

Is there a way to call a function in another language?

Yes. The opcode is CALLP. Or in free-format:

myfunction(myFirstArg: mySecondArg) ;

Of course, you will need the prototype et cetera.
