Delphi in a Nutshell

Name

$OpenStrings Compiler Directive

Syntax

{$P+}             // default
{$OpenStrings On} // default
{$P-}
{$OpenStrings Off}

Scope

Local

Description

The $OpenStrings compiler directive treats all string-type parameters as OpenString parameters. If $LongStrings is enabled, Delphi ignores $OpenStrings.

The $OpenStrings directive affects only parameters declared with the string type, and only when long strings are disabled. Even if $OpenStrings is enabled, you can use the OpenString type to declare an open string parameter.

$OpenStrings exists for backward compatibility. New Delphi programs should use long strings instead of short strings.
