Input parameter attributes

A RESTful web service function can have input parameters.

The type of input parameter is defined by the ATTRIBUTES property. Table 1 lists the types. Additional parameters can be specified to provide a name or description; and depending on the parameter type, other attributes might identify the parameter as optional or specify a supported data format.

PUBLIC FUNCTION function-name(
    parameter-name INTEGER ATTRIBUTES(WSHeader, WSName = "id"),
    parameter-name INTEGER ATTRIBUTES(WSParam, WSDescription = "Value to be used")
    # ...
    )
    # ...
END FUNCTION
