пример их хелпа к методу DictFieldGroup.numberOfFields:

DictFieldGroup t = new DictFieldGroup(_tableId, _fieldGroupName);
DictField f;
int i;
fieldId id;
;
if (t)
{
    for (i=1; i<=t.numberOfFields(); i++)  // numbering starts at 1
    {
        id = t.field(i);
        f  = new DictField(dict.tableName2Id(_tableName), id);
        if (f) print 'Field: ' + f.name() + ' (' + int2str(id) + ')';    
        else  print 'MethodName: ' + t.methodName(id) + ' (' + int2str(id) + ')';
    }
