How do I use multiple joins in an X++ select statement?

SalesTable    salesTable;
CustTable     custTable;
DirPartyTable party;

while select salesTable
    join custTable
        where custTable.AccountNum == salesTable.CustAccount
    join party
        where party.RecId == custTable.Party
{
    info(strFmt('%1 - %2', salesTable.SalesId, party.Name));
}
