Procedure Declarations

If a procedure declaration includes LANGUAGE on page 14-8, it must also include

public-name-spec.

parameter-list

param-name

is the identifier of a formal parameter. A procedure can have up to 32 formal

parameters.

param-pair

is a pair of formal parameter identifiers that comprise a language-independent

string descriptor in the form:

string

is the identifier of a standard or extended STRING simple pointer. The

actual parameter is the identifier of a STRING array or simple pointer

declared inside or outside a structure.

length

is the identifier of a directly addressed INT simple variable. The actual

parameter is an INT expression that specifies the length of string, in

bytes.

proc-attribute

is a procedure attribute, as described in Procedure Attributes on page 14-5.

param-spec

specifies the parameter type of a formal parameter and whether it is a value or

reference parameter, as described in Formal Parameter Specification on

page 14-10.
