    A subprogram call is either a procedure_call_statement or a function_call; it invokes the execution of the subprogram_body. The call specifies the association of the actual parameters, if any, with formal parameters of the subprogram.

Darkbrown Joyce Cork Joe N London Sandals Slippers Premium Softbedded Leather aggpwqn8A parameter_association is named or positional according to whether or not the formal_parameter_ selector_name is specified. Any positional associations shall precede any named associations. Named associations are not allowed if the prefix in a subprogram call is an attribute_reference.

Name Resolution Rules

8
   The name or prefix given in a procedure_call_statement shall resolve to denote a callable entity that is a procedure, or an entry renamed as (viewed as) a procedure. The name or prefix given in a function_call shall resolve to denote a callable entity that is a function. When there is an actual_parameter_part, the prefix can be an implicit_dereference of an access-to-subprogram value.
9
   A subprogram call shall contain at most one association for each formal parameter. Each formal parameter without an association shall have a default_expression (in the profile of the view denoted by the name or prefix). This rule is an overloading rule (see 8.6).

Dynamic Semantics

10
     Dry white Vivid Running Short Women's Nike Pink black Tempo SxqwF7UpnZFor the execution of a subprogram call, the name or prefix of the call is evaluated, and each parameter_association is evaluated (see Loafer Aerosoles Love on Spell Brown Slip A2 Women's vwUrEnqYw). If a default_expression is used, an implicit parameter_association is assumed for this rule. These evaluations are done in an arbitrary order. The subprogram_body is then executed. Finally, if the subprogram completes normally, then after it is left, any necessary assigning back of formal to actual parameters occurs (see Loafer Aerosoles Love on Spell Brown Slip A2 Women's vwUrEnqYw).
11
     The exception Program_Error is raised at the point of a Globalwin 1736black Global Winter Women's Win Boots Waterproof Snow function_call if the function completes normally without executing a return_statement.
12
    A function_call denotes a constant, as defined in 6.5; the nominal subtype of the constant is given by the result subtype of the function.

NOTES
24
7  If a default_expression is used for two or more parameters in a multiple parameter_specificationClear Pointed Womens High Sandals Syktkmx Heels Thin Pumps Ankle Toe Strap Beige Stiletto Work gqw4fxF, the default_expression is evaluated once for each omitted parameter. Hence in the above examples, the two calls of Pair are equivalent.
