~~Title: Record iteration~~

It's possible to iterate all records of a databook with different techniques. It's a performance decission what's best. Just reading is fastest.

You decide if you iterate for reading or for changing records. An iteration 

==Iterate with optional record change (Solution 1)==
<file java>
int masterRow = mdbMaster.getSelectedRow();
int detailRow = mdbDetail.getSelectedRow();

boolean resetSelection = false;

try
{
    for (int i = 0; i < mdbMaster.getRowCount(); i++)
    {
        for (int j = 0; j < mdbDetail.getDataPage(mdbMaster.getDataRow(i)).getRowCount(); j++)
        {
            if (changeData)
            {
                mdbMaster.setSelectedRow(i);
                mdbDetail.setSelectedRow(j);
                
                resetSelection = true;
            }
        }
