/**
 * We need this one in case no "exp" is returned from MDB.
 * The standard answer would something like this:
 * <blockquote><code>-var-list-children var2
 *  ^done,numchild="6",children={child={name="var2.0",exp="0",numchild="0",type="char"},child={name="var2.1",exp="1",numchild="0",type="char"},child={name="var2.2",exp="2",numchild="0",type="char"},child={name="var2.3",exp="3",numchild="0",type="char"},child={name="var2.4",exp="4",numchild="0",type="char"},child={name="var2.5",exp="5",numchild="0",type="char"}}
 * </code></blockquote>
 * But early versions of MDB skipped the exp attribute, which
 * caused all kinds of weird behaviour.
