Detailed Description

Generate and return the location of the first occurrence of a non-whitespace character in the input string, from left to right.
Otherwise, return 0 if the input string is all whitespace characters.

Parameters

[in] str : The input scalar or array of arbitrary rank of type character of default kind SK.

Returns: locNonSpace : The output scalar or array of the same shape as the input str of type integer of default kind IK whose value is the location of the first occurrence of the whitespace character in the input string from the left to the right.
