Operation

       GENMOD-

       GENMOD ISSUES THE START (NO) COMMAND TO FINISH LOADING OF
       OBJECT PROGRAMS. NEXT ERASE THE OLD MODULE IF IT EXISTS.
       THE START AND ENDING LOCATIONS ARE DETERMINED FROM THE
       USER OPTIONS 'TO' AND 'FROM' OR BY DEFAULT. THE DEFAULT
       START IS THE ADDRESS OF THE FIRST LOADER TABLE NAME, THE
       DEFAULT END IS THE CURRENT SETTING OF LOCCNT IN NUCON.
       AN EIGHTY BYTE RECORD IS WRITTEN AS THE FIRST RECORD OF THE
       THE MODULE. THIS RECORD CONSISTS OF THE NUCON LOADER INFORMA-
       TION. NEXT THE TEXT INFORMATION IS WRITTEN TO THE MODULE
       FILE IN VARIABLE SIZE RECORDS UP TO 65535 BYTES. IF THE
       MODULE IS NOT FOR A TRANSIENT ROUTINE AND NOMAP WAS NOT
       SPECIFIED THE LOADER TABLE IS WRITTEN AS THE LAST MODULE
       FILE RECORD. CLOSE THE NEW MODULE FILE AND RETURN TO THE
       CALLER.

       LOADMOD-

       LOADMOD CHECKS FOR THE EXISTENCE OF THE REQUESTED MODULE
       THEN READS THE TEXT INFORMATION INTO THE LOCATIONS SET
       UP WHEN THE MODULE WAS CREATED. THE MODULE NAME IS
       STORED IN THE APPROPRIATE NUCON LOCATION. IF THERE IS
       A LOADER TABLE RECORD IN THE MODULE IT IS READ INTO
       THE LOADER TABLE LOCATION IN STORAGE. SELECTED LOADER
       INFORMATION IS STORED IN NUCON. RETURN TO CALLER
