     * B on to repeat inner test -- for scoping
     * C on to print correct results
     * D on to repeat test without reading new detail
     * E on to halt on errors
     *
     * Halts:
     * 99 in A-star and B-star if no more detail records and no header.
     *    Pushing start tries again.  If reading detail from tape it
     *    is nonetheless possible to read more detail from cards here.
     * 86 in A-star and B-star if tape error.  Pushing start tries again.
     *    It is possible to read more detail from cards here.
     * 458 in A-star and 490 in I-star if test error and SS E on.  Pushing
     *    start continues, depending on SS D.
     *
     * Set a word mark in 1.  Read detail records from cards if there
     * are any. Otherwise halt if 81 is not GM (program is not loaded
     * from tape). Otherwise read a record from tape into 1. If 80 is 
     * A, branch to 1.
     * 
     * Print the first two if headpr is not blank.  Otherwise skip them.
