; IDENTIFICATION: CSS/395/PGM
; VERSION: 02
; DATED: 791101/FR
;
; THE AMOS_MASTERCLEAR_UTILITIES PROGRAM (AMU) RESIDING IN THE UPPER
;2K_WORDS PROM OF MEMORY SECTION 0 WILL SERVE THE USER OF THE CR80 WITH
;A RANGE OF UTILITIES. THIS AIM NOT ONLY AT PROGRAMMERS BUT ALSO AT
;MAINTENANCE PERSONNEL.
; ONLY MEMORY LOCATIONS:
; #200-#221 INCL
;WILL BE DESTROYED UPON EITHER MASTER CLEAR OR EMERGENCY ACTION, THOUGH
;ONLY AS LONG AS THE USER RESTRICT HIMSELF TO THE FOLLOWING UTILITIES:
; COPY, DUMP, IO_UTILITIES, MEMORY_CHECK, PATCH, SEARCH
; XECUTE, SET_PARITY (,AND OPTIONS).
; HOWEVER THE AMU_PROGRAM WILL NEVER CLAIM BUT THE LOWER #247 WORDS OF
;MEMORY EXCEPT FOR THE CPU_TEST WHICH REQUIRES AN ADDITIONAL 4K_RAM
;STARTING AT #1000.
;THIS IMPLIES THAT FD_BOOT_FILES CAN HAVE THEIR LOADING ADDRESS (START)
;FROM #0248 AND UPWARDS. (CROSSING PAGE_BOUNDARIES DURING FD_LOAD WILL
;RESULT IN A PAGE SHIFT AND CONTINUATION FROM #0000 THAT PAGE).

; IF A PAGE OTHER THAN PAGE 0 IS DESIRED, IT MUST FOLLOW IMMEDI-
; ATELY AFTER THE COMMAND, I.E.
; <COMMAND><PAGE> <....
; ONLY COMMANDS MARKED WITH '*' CAN HAVE PAGE SELECTION.
;
; <---> HEXADECIMAL DATA_WORD:
; AN ENTERED HEXADECIMAL DATA WORD CAN BE ANY COMBINATION OF
; HEXA-DECIMAL CHARACTERS. THOUGH ONLY THE LAST ENTERED FOUR ARE
; ACCEPTED. ZEROES WILL AUTOMATICALLY BE FILLED IN IF LESS THAN
; FOUR HEX CHARACTERS HAVE BEEN ENTERED.
; HEX DATA_WORDS ARE SEPARATED BY ANYTHING BUT '0123456789ABCDEF'
; AND CARRIAGE RETURN <CR>.
; <CR> FLAGS END_OF_DATA.
; <---><DEL> IMPLIES THAT THE ENTERED HEXADECIMAL (WORD (ONE) IS
; REJECTED.
; NOTE THAT +0 ALWAYS IS INTERPRETED AS 64K (ONE PAGE).
