  Yes

  table.BlobField.CREATEOUTSTREAM(ostream);
  bstr.WRITE(ostream);
  

  
  

  table.BlobField.CREATEINSTREAM(istream);
  bstr.READ(istream);

  Thanks.
  
  But I have got a text variable.
  
  lets say "txtA" being passed from some other source to a function
  Now I want to load it into a stream to pass it xml port.
  
  so what needs to be done.
  
  txtA.CREATEINSTREAM(ostream);
  bstr.READ(istream);
  
  right?

  There's a table that you can use for this purpose, called TempBLOB. Add a temporary record variable based on that table, and use its methods:

  TempBlob.Blob.CREATEOUTSTREAM(outstr);
  TempBlob.Blob.CREATEINSTREAM(instr);
  

  Now you can use other automation to actually populate the out and instreams. Read the outstream from a big text, and use the outstream as the source for your XMLPort.
  
  You would use CREATEOUTSTREAM only for outstreams, not instreams. For that you would use CREATEINSTREAM. By using the TempBlob table, when you read the instream into the Blob field, you can set its value from an instream, and use it to create an outstream, based on the same field.

  hI thanks for your help.
  I am just new to nav cal coding...
  
  
  ProcessCustomers(InputXML : BigText) status : Boolean
  
  tempRec.Blob.CREATEINSTREAM(XMLInStream);
  InputXML.READ(XMLInStream);
  XMLPORT.IMPORT(123456751,XMLInStream);
  status := TRUE;

  Yes, you are reading the blob into the BigText instead writing it into outstream and reading it through instream...
