02600	HDRFIL is created from HEAD and part of GOGOL.  It contains all
02700		index and bit and AC declarations, as well as the macros
02800		which are used in the library.  All comments and blank
02900		lines are squeezed out.  It is not created unless some
03000		need for it is exhibited.
03100	DOHEAD is created if needed to create the HEAD entry in the library,
03200		an INTERNALed symbol table of the user-table things.
03300	SCISS.SAI reads this file to get its instructions.  To read the
03400		above stuff, consider an example:  If SAIPTC is to be
03500		compiled, From IOSER will be extracted the code for PTC,
03600		named SAIPTC.FAI.  This will be assembled with HDRFIL to
03700		get SAIPTC.REL.  If the first file is not HDRFIL, no extrac-
03800		tion will be performed.
