Hi nathan I'm sorry,I forgot to paste this code:
var TINData = new StructType();
TPOSData.defineProperty('Value', new fixedString(8+1));
TPOSData.defineProperty('Type', new fixedString(1+1));
TPOSData.defineProperty('Id', 'int');
TPOSData.defineProperty('Id', 'string');
var TOUTData = new StructType();
TOUTData.defineProperty('Telephone', new fixedString(11+1));
TOUTData.defineProperty('CallType', new fixedString(3+1));
TOUTData.defineProperty('CallResult', new fixedString(2+1));
TOUTData.defineProperty('Description', new fixedString(24+1));
I am getting a reference to the myTOUTData to inspect the values, to see if
they are correctly in their positions ,so I am able to parse the result.
I am developing using eclipse with node plugin , and I have usually this
error "Malloced operator new Allocation failed - process out of memory"
thank you for your help
Leo
