https://docs.servicenow.com/bundle/vancouver-application-development/page/script/server-scripting/concept/c_ScriptableServiceCatalogVariables.html

Example to access variables of GlideRecord for the Task table

var now_GR = new GlideRecord('sc_req_item'); 
if (now_GR.get('635a1f5387320300e0ef0cf888cb0b73')) { 
    var variables = now_GR.variables.getElements(); 
    for (var i=0;i<variables.length;i++) { 
        var question = variables[i].getQuestion(); 
        gs.log(question.getLabel() + ":" + question.getValue()) 
    } 
}

Example to access a multi-row variable set of GlideRecord for the Task table

var now_GR = new GlideRecord('sc_req_item');
now_GR.get('02c38dcd87013300e0ef0cf888cb0bb2');

var vars = now_GR.variables.getElements(true);

for (var i=0; i<vars.length; i++) {
    var now_V = vars[i];
    if (now_V.isMultiRow()) {
        var rows = now_V.getRows();
        for (var j=0; j<now_V.getRowCount(); j++) {
            var row = rows[j];
            var cells = row.getCells();
            for (var k=0; k<cells.length; k++) {
                var cell = cells[k];
                gs.info(cell.getLabel() + ":" + cell.getCellDisplayValue())
            }
        }
    }
}
