53

54
* Structure of this Record must be equal with subtype of array.
55

56
* file and storage of array subtype. We return helper storage of this subtype with
57
* default values (only determines structure).
58
* 5. We iterate through CSV file. For every line we fill data into helper storage and
59
* copy this helper storage to storage represents included array.
