7.2 Defining an array
7.2.1 Accessing the value of an array element
Description
The value of an array access operation can be transferred with property Value (identifier.val).
The line index (line number of the array) and the column index (column number of the array)
each begin at 0. If a line index or column index is outside the array, the value 0 or a blank
string is output and the ERR variable is set to TRUE. Variable ERR is also set to TRUE if a
search concept cannot be found.
