0874 * CODE. IF THE PROGRAMMFR DESIRES TO LOAD CODE INTO A BASE 0875 * SECTOR, HE MUST CHECK THE '*BASE' LINE OF THE MEMORY MAP TO 0876 * SEE IF TABLE AND PROGRAM OVERLAP. 0877 * 0878 * 5. THE LOADER IS NORMALLY LOADED TO OCCUPY THE LAST 0879 * FOUR SECTURS OF MEMORY (FIVE SECTORS IF MAGNETIC TAPE AND/OR 0880 * CARD COMPATIBILITY REQUIRED.) HOWEVER, IT CAN BE LOADED 0881 * WITH LOWER ORIGIN TO GIVE UPPER LOADING CAPABILITY. 0882 * SINCE NO PROGRAM MAY BE LOADED ABOVE COMMON, THE COMMON 0883 * ORIGIN (SYMBOLIC LOCATION "FIL7") (XX000+2000) SHOULD 0884 * BE RAISED WHEN THIS 1S DONE. 0885 * 0886 * 6. A SUBPROGRAM MAY NOT BE SPLIT BETWEEN TAPES, 0887 * 0888 * 7. IN A STRING OF INSTRUCTIONS GENERATED BY THE DDP-116 FORTRAN 0889 * IV COMPILER, NO INSTRUCTION IN THE STRING MAY HAVE BEEN 0890 * DESECTORED INTO A BASE SECTOR OTHER THAN THE BASE SECTOR 0891 * IN EFFECT WHEN THE STRING VALUE IS ENCOUNTERED. NO ERROR 0892 * INDICATION WILL BE GIVEN IF THIS RESTRICTION IS VIOLATED, AND 0893 * THE RESULT IS UNPREDICTABLE. 0894 * 0895 * 8. COMMON MAY NOT BE USED BEFORE IT IS DEFINED. 0896 * 0897 * 9. SUBPROGRAM CALLS ARE NOT NECESSARILY DESECTORED. IF THE 0898 * SUBPROGRAM ENTRY POINT IS IN THE SAME SECTOR AS THE CALL, 0899 * THE CALL WILL BE LINKED DIRECTLY TO IT, AND NO INDIRECT 0900 * WORD WILL BE CREATED IN THE BASE SECTOR. 0901 * 0902 * 10. FORTRAN COMPILED PROGRAMS MAY NOT STRING INTO CODE IN 0903 * A BASE SECTOR. THIS ERROR CANNOT BE DETECTED, AND IF IT 0904 * OCCURS, THE RESULT IS UNPREDICTABLE. 0905 * 0906 * 0907 * 0908 * 0909 * 0910 * 0911 * 0912 * 0913 * 0914 * 0915 * 0916 ********************************************************************** 0917 EXD ENTER EXTENDED ADDRESSING 0918 * 0919 SUBR INHALT,HHHT LOCATION OF INPUT DEVICE HALT 0920 * 0921 REL RELOCATE ONLY IN UNITS OF SECTORS. 0922 000000 ORG EQU * MAXIMUM ORIGIN FOR THIS LOADER IS '74000. 0923 00000 BSS '50 SYMBOL TABLE AREA
