Populate array with "occurs any"

I have just started using Visual Cobol in Microfocus Visual Studio 2012.

My code needs to read records and update an array named 'ItemsField' in a web service reference file(See attached Word file for layout of the input file and the web service references file). The array I want to populate is described as having  'occurs any' and is named 'ItemsField' in the web service references file.

My question is: How do I add data to this array and update the number of occurs?
