Error Text

In call to function My_sum, the first parameter, X, should be in ascending order.

Cause

You have called a function that requires the values in the array passed to the parameter to be in ascending order, but the values in the array were not in ascending order.

For a function parameter declared as follows, Function My_sum( X : ascending ) calling the function

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], i.e., from 25 to 24.

The "... along the implicit index" message appears when the dimension is the implicit or null dimension, not corresponding to any index object.
