 182  * The 'size' pass determines the size of each component and assigns the extent number
 183  * for that component.
 184  *
 185  * The 'generate' pass will adjust the contents and pointers as required now that extent
 186  * numbers are assigned.  In some cases, the contents of the record are also generated.
