# Group of Functions for Working with Arrays

[Arrays](/en/docs/basis/variables#array_define) are allowed to be maximum four-dimensional. Each dimension is indexed from 0 to dimension_size-1. In a particular case of a one-dimensional array of 50 elements, calling of the first element will appear as array[0], of the last one - as array[49].

| Function | Action |

| ArrayBsearch | Returns index of the first found element in the first array dimension |
| ArrayCopy | Copies one array into another |
| ArrayCompare | Returns the result of comparing two arrays of  simple types  or custom structures without  complex objects |
| ArrayFree | Frees up buffer of any dynamic array and sets the size of the zero dimension in 0. |
| ArrayGetAsSeries | Checks direction of array indexing |

| ArrayRange | Returns the number of elements in the specified dimension of the array |
| ArrayResize | Sets the new size in the first dimension of the array |
| ArrayInsert | Inserts the specified number of elements from a source array to a receiving one starting from a specified index |
