I work with MUMPS as my work programming language. Assuming you had an array of 10 numbers, to get the sum you would do something like this:
F I=1:1:10 S ARR(I)=I ; Stores 1-10 in array ARR
F I=1:1:10 S SUM=SUM+ARR(I)
W !,SUM ; Writes sum
In Klong you would do as follows:
arr::1+!10 :" Initializes list arr with values of 1-10"
.p(+/arr) :" .p() prints and +/arr sums all elements of the list"
I always thought that MUMPS was terse, but for certain things at least, it doesn't hold a candle to Klong. Of course, I thought Minnesota was green until I saw Wisconsin. And now I live in Washington state.
