This Guide Article has been written for Version 2.1 of the DATAFLOW Software. For Previous Releases use the version selection in the navigation bar at the top of this page.

Certain keywords must not be used as element names in the DATAFLOW Designer. If such a name is used, an error is generated during the Model Validation and no code can be generated.

The reserved keywords ensure that no identifier in the generated code will have the same name as a reserved keyword of a supported programming language.

NOTE: All keywords are given in lower case. Because names are normalized, the reserved keywords are case insensitive. For example, the name 'for' 'For' and 'FOR' are all reserved keywords and must not be used.

C++ Reserved Keywords

For the C++ language, the list of keywords is based on the C++ standard.

The following keywords must not be used for any element name in the DATAFLOW model:

alignas, alignof, and, and_eq, asm, atomic_cancel, atomic_commit, atomic_noexcept, auto, _alignas, _alignof,
_atomic, bitand, bitor, bool, bool_t, break, _bool, case, catch, char, char_t, char8_t, char16_t, char32_t,
