as sudhanshu already pointed next()

var com = new GlideRecord('core_company');
com.addQuery('name','ACME Australia');
com.setLimit(1);
com.query();
while(com.next()){
com.u_type = "00aba08d3790200044e0bfc8bcbe5dfc";
com.update();
}

Oh I see you wanted it in a background script:

var valuesToSet = [];
var table = ''; //fill in the table
var sysID = ''; //fill in the sys id of the record you want to update
valuesToSet.push(current.assigned_to.toString());//example to add assigned to
valuesToSet = new ArrayUtil().unique(valuesToSet);

var gr = new GlideRecord(table);
if (gr.get(sysID)) {
    gr.u_test = valuesToSet.toString();
    gr.update();
}
