They denote the initial address in the page where the next file or program will be written using HSAVEP, HCRFLAS and HCRFLD. Their values will vary as more programs or content is written to the HRAM page, thus should not be overwritten by HEPINI – or else the HEPAX FileSys catalog will become corrupt."
