The IEC Operators and additional, norm-extending \ functions

All IEC operators are supported. In contrast with the standard functions (see Appendix D of the 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 (see Arithmetic Operators), ADR and BITADR (see Address Operators).

Operators are used like functions in POU.
