Pragma Volatile (GNAT Reference Manual)

### 2.204 Pragma Volatile ¶

Syntax:

    pragma Volatile (LOCAL_NAME);

This pragma is defined by the Ada Reference Manual, and the GNAT implementation is fully conformant with this definition. The reason it is mentioned in this section is that a pragma of the same name was supplied in some Ada 83 compilers, including DEC Ada 83. The Ada 95 / Ada 2005 implementation of pragma Volatile is upwards compatible with the implementation in DEC Ada 83.
