Hi,
here is a commented program stanza
var v = this.getField("myTextField").value;
// Get the contents of the file attachment with the name "MyNotes.txt"
var oFile = this.getDataObjectContents("MyNotes.txt");
// Convert the returned stream to a string
var cFile = util.stringFromStream(oFile, "utf-8");
// Append new data at the end of the string
cFile += "\r\n" + v;
// Convert back to a stream
oFile = util.streamFromString( cFile, "utf-8");
// Overwrite the old attachment
this.setDataObjectContents("MyNotes.txt", oFile);
// Read the contents of the file attachment to a multiline text field
var oFile = this.getDataObjectContents("MyNotes.txt");
var cFile = util.stringFromStream(oFile, "utf-8");
this.getField("myTextField").value = cFile;
