array 
Reference to an array
indices 
n-tuple of indices where n is the number of dimensions of the array array

Further information
1. These functions set the value of an array entry that corresponds to a given tuple of indices for the given array.
2. The first form of this function selects the right value type (integer, real, string or boolean) based on the type of the array. If applied to an array of any other type, the reference to the object is returned in the value parameter and the function returns 2.
3. When setarrvalstr is applied to an array of a type published by a module, it uses dsotypfromstr for performing the assignment.
