Expanding the Operator Interface (BE1)
3 Syntax
The line index (line number of the array) or column index (column number of the
array) each start at 0.
If a line index or column index points to outside the array, the value 0 or a blank
string is output and error variable ERR set to TRUE.
Error variable ERR is also set to TRUE if a search concept cannot be found.
"Direct" access mode
With "Direct" access mode (M = 0), the array is accessed with the line index in Z
and the column index in S. Compare mode C is not evaluated.
"Search" access mode
In the case of access mode M = 1, 2 or 3, the search always commences in line 0
or column 0.
Compare mode
When compare mode C = 0 is used, the content of the search line or search
column must be sorted in ascending order. If the search concept is smaller than the
first element or greater than the last, the value 0 or a blank string is output and the
error variable ERR is set to TRUE.
When compare mode C = 1 is used, the search concept must be present in the
search line or search column. If the search concept cannot be found, the value 0 or
a blank string is output and the error variable ERR is set to TRUE.
