;
;FASTGO 1.1 : A PROGRAM DESIGNED TO MAKE IT EASIER
;TO MOVE TO A SPECIFIC, LABELED DRIVE/USER AREA.
;INTENDED MAINLY FOR HARD DISK SYSTEMS, BUT SHOULD
;WORK EQUALLY WELL ON ANY 2.2 SYSTEM. ALLOWS PASSWORD
;PROTECTING AND CHAINING TO ANOTHER PROGRAM AFTER
;ENTERING NEW USER-AREA. FOR USAGE, TYPE GOTO.
;
;***************************************************
;REVISIONS:
;
;05/06/84 VERS. 1.1:
;          ADDED RELOCATION OF CODE TO HIGHMEM SO
;          THAT A .COM FILE MAY BE LOADED AND RAN FROM
;          100H. ADDED DRIVE AND USER # DISPLAY TO
;          USAGE ROUTINE. (JHW)
;***************************************************
;
;WHEN EXECUTED, THIS PROGRAM DOES THE FOLLOWING:
;
;1. RELOCATES ITSELF TO HIGH MEM (SET BY USER).
;2. CHECKS FOR INPUT, PRINTS OPTIONS AND QUITS IF NONE.
;3. EVALUATES INPUT, SEEKING A MATCH FROM THE TABLE.
;4. IF NO MATCH FOUND, TELL USER, DISPLAY OPTIONS AND QUIT.
;5. ON MATCH, CHECK FOR PASSWORD STATUS AND GET IT IF NEEDED.
;6. IF PASSWORD DOESN'T MATCH, ABORT.
;7. SELECT SPECIFIED USER-AREA.
;8. IF RUNCOM = TRUE, LOAD AND RUN A .COM FILE.
;9. EXIT TO SYSTEM.
;
;NOTE: I'VE SEEN A UTILITY OF THIS TYPE ON OTHER
;SYSTEMS, BUT HAVE NEVER BEEN ABLE TO LOCATE THE
;SOURCE CODE. SO I WROTE THIS ONE. THIS CODE IS CRUDE,
;BUT IT DOES THE JOB. I'M PLANNING ON MOVING UP TO A
;HARD DISK SYSTEM IN THE FAIRLY NEAR FUTURE SO I'M
;GATHERING UTILITIES FOR IT. 
;
;RENAME THIS FILE TO GOTO.COM.
;  GOTO           DISPLAYS USAGE AND VALID USER-AREAS
;  GOTO USER-AREA MOVES TO USER-AREA. IF PASSWORDED,
;                 GETS SAME FROM USER BEFORE MOVING.
