I'm going to assume you are speaking precisely in that sentence.
I'm going to give you a C program that merely lops off the last six lines,
rather than reformatting from 66-line pages to 60-line pages with one-
inch top and bottom margins.

If there's a way faster than this, you've a better compiler
than I, Gunga Din:

    /* Well, not forever, it's not got function prototypes, so  *
     * it isn't ANSI...						*/

    #include <stdio.h>
    extern char *gets();
    extern int puts();

    /* No arguments.  It reads stdin and writes stdout. */
    main()
    {
            int lineno=0;
            char line[80];

	    /* One statement.  No sweat.  The sed	*
	     * script is a novella in comparison.	*/
            while( gets(line) != NULL )
                    if ( ++lineno < 61 )
                            puts(line);
                    else if ( lineno == 66 )
                            lineno = 0;
    }
