Description
In Delphi code, Inc adds one or N to the variable X.
X is a variable of an ordinal type (including Int64), or a pointer type if the extended syntax is enabled.
N is an integer-type expression.
X increments by 1, or by N if N is specified; that is, Inc(X) corresponds to the statement X := X + 1, and Inc(X, N) corresponds to the statement X := X + N. However, Inc generates optimized code and is especially useful in tight loops.
Note: If X is a pointer type, it increments X by N times the size of the type pointed to.
