Example 1: Create and Destroy Simple JSON Object

*--------------------------------------------------------------
* This example creates a simple JSON object, adds a data field 
* to it, and then calls RXS_DestroyJson() to clean up.

Data Structures

RXS_CreateJsonDS_t
RXS_JsonStructureDS_t

`D RXS_CreateJsonDS_t... D DS Qualified Template Inz`
`D ReturnedErrorInfo... D LikeDS(RXS_ReturnedErrorInfoDS_t) Inz`
`D DataStructureType... D 5I 0 Inz(RXS_DS_TYPE_CREATEJSON)`	Internal use only
`D OnErrorMessageType... D 5I 0`
`D Prettify N Inz(RXS_NO)`	If set to RXS_YES, JSON retrieved with RXS_GetJsonString() will be formatted with whitespace to be "pretty" and more human readable. If set to RXS_NO, JSON will be returned in a compact form with as little whitespace as possible.
`D JsonStructureType... D N Inz(RXS_JSON_STRUCTURE_OBJECT)`	If set to RXS_JSON_STRUCTURE_OBJECT, the JSON document being created will begin with a root JSON object. If set to RXS_JSON_STRUCTURE_ARRAY, it will begin with a root JSON array.
`D JsonStructure@... D * Inz(*Null)`	Internal use only
`D InputCcsid... D 10I 0 Inz(RXS_CCSID_JOB)`	Specifies the CCSID of the data being passed into the JSON composition subprocedures. Default is job CCSID.
`D OutputCcsid... D 10I 0 Inz(RXS_CCSID_JOB)`	Specifies the CCSID that the JSON will be output as from RXS_GetJsonString(). Default is job CCSID.
