Error Text

In call to function My_sum, the first parameter, X, should be ascending along J.

Cause

You have called a function that requires the values in the array passed to the indicated parameter to be increasing along the given index, but they are not.

Suppose a function is declared as follows:

Function My_sum( X : ascending ; I : Index )

Now suppose you have an array:

X :=

J →
1	2	3	4	5	6
15	18	25	24	30	45

If you were to evaluate:

My_sum( X, J )

This error would result since the values decrease from X[I=3] to X[I=4].
