All IEC operators are supported. In contrast with the standard functions (see Appendix D of the Standard library⮫ “Standard library”), these operators are recognized implicitly throughout the project.

Besides the IEC operators also the following operators are supported which are not prescribed by the standard: INDEXOF and SIZEOF ⮫ “Arithmetic operators”, ADR and BITADR ⮫ “Address operators”.

Operators are used like functions in POU.
