mapp Services V5.16
The interpreter supports directly derived data types from an array as well as nested array types (arrays of arrays).
To access an element of the nested array type, multiple sets of indexing brackets are required, one for each "ARRAY [...] OF" specification, e.g. [...][...].
TYPE
ArrayType : ARRAY [1..10] OF DINT;
MatrixType : ARRAY [1..10] OF ArrayType; (* An array of arrays *)
MultiType : ARRAY [1..10, 1..10] OF DINT; (* A 2-dimensional array *)
END_TYPE
VAR
Matrix : MatrixType;
Multi : MultiType;
END_VAR
PROGRAM _MAIN
Matrix[1][2] := Multi[1, 2];
END_PROGRAM
