7.2 Defining an array
Access mode
● "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.
Mode M
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.
