Syntax Coloring

Source code is colored in the DVT editor. Some language constructs are colored based on a syntactical analysis of the code, while others require a more elaborate semantic analysis, as detailed in the table below. Semantic coloring is only performed when the source code is compiled.

Note

Inside macro definitions, macro calls and PSL vunits, only syntactic coloring is performed.
