From RM95, Annex L:

35 pragma Storage_Size(expression); � See 13.3.

And from RM95 3.13:

59 For a prefix T that denotes a task object (after any implicit
dereference):

60 T�Storage_Size Denotes the number of storage elements reserved for
the task. The value of this attribute is of the type universal_integer. The
Storage_Size includes the size of the task�s stack, if any. The language
does not specify whether or not it includes other storage associated with
the task (such as the �task control block� used by some implementations.)
If a pragma Storage_Size is given, the value of the Storage_Size attribute
is at least the value specified in the pragma.

61 A pragma Storage_Size specifies the amount of storage to be reserved
for the execution of a task.

Syntax

62 The form of a pragma Storage_Size is as follows:

63   pragma Storage_Size(expression);

64 A pragma Storage_Size is allowed only immediately within a
task_definition.

Name Resolution Rules

65 The expression of a pragma Storage_Size is expected to be of any
integer type.

Dynamic Semantics

66 A pragma Storage_Size is elaborated when an object of the type
defined by the immediately enclosing task_definition is created. For
the elaboration of a pragma Storage_Size, the expression is evaluated;
the Storage_Size attribute of the newly created task object is at least
the value of the expression.
67 At the point of task object creation, or upon task activation,
Storage_Error is raised if there is insufficient free storage to
accommodate the requested Storage_Size.
