Syntax

_constantName = staticExpr

Description

This is a non-executable statement which assigns the value of staticExpr to the symbolic constant indicated by _constantName. The _constantName must indicate a name which was not defined anywhere previously in the program, and which is different from all pre-defined FB symbolic constant names. The name must be preceded by an underscore ( _ ) character. The staticExpr must be a "static integer expression"; it cannot contain any variables nor function references.

The constant declaration statement is one of several ways to assign values to symbolic constant names. Other ways include using the DIM RECORD statement and using the BEGIN ENUM statement.
