Delphi in a Nutshell

Name

$StackFrames Compiler Directive

Syntax

{$W-}              // default
{$StackFrames Off} // default
{$W+}
{$StackFrames On}

Scope

Local

Description

The $StackFrames directive causes the compiler to generate a stack frame for every subroutine call (except for subroutines you write in assembly language). The default is that stack frames are created only when they are needed for local variables.

Some debugging tools require stack frames. If you are not using such a tool, you can leave the default setting, which results in slightly more efficient code.
