11.2.5 Structures
Structures are created as objects in the Object Organizer under the register card
Data types. They begin with the keywords TYPE and STRUCT and end with
END_STRUCT and END_TYPE.
The syntax for structure declarations is as follows:
TYPE :
STRUCT
.
.
END_STRUCT
END_TYPE
is a type that is recognized throughout the project and can be used
like a standard data type.
Interlocking structures are allowed. The only restriction is that variables may not be
placed at addresses (the AT declaration is not allowed!).
Example for a structure definition named Polygonline:
TYPE Polygonline:
STRUCT
Start:ARRAY [1..2] OF INT;
Point1:ARRAY [1..2] OF INT;
Point2:ARRAY [1..2] OF INT;
Point3:ARRAY [1..2] OF INT;
Point4:ARRAY [1..2] OF INT;
End:ARRAY [1..2] OF INT;
END_STRUCT
END_TYPE
