Re: [Ftpapi] Optional XML Labels



Jon,

Sorry, but what do you think would not work earlier that V7.2? The 4MB
buffer? It is heap storage dynamically allocated by WSDL2RPG and
controlled by the following procedure call:

   hSoapPart =
      MessageContext_getSoapPart(hMsgCtx: 1024*1024*4); // 4 MB cache

Regards,

Thomas.
