Inc

Increments an ordinal value by one or N.

Structure

Inc(var X [ ; N: Longint ] );

Parameters

Description

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. |
