listintersect/3—determine the common elements in two lists
The listintersect/3 operation determines the common elements in two lists. The syntax for this function is as follows:
listintersect($LIST1,$LIST2,$LIST)
$LIST=listintersect($LIST1,$LIST2)
$LIST=listintersect($LIST1,$LIST2)
listintersect/3 arguments
Argument | Mode | Type | Description |

$LIST2 | Input | LIST_OF ANY | Specifies the second list to be compared with the first list |
$LIST | Output | LIST_OF ANY | List of common elements of $LIST1 and $LIST2 |
