S U P E R M O N + 64 In the following discussion, keyboard input in designated by brackets. SUPERMON+ is a new version of 'SUPERMON' the reason for the new version is to provide identical commands to those of the built-in monitor of the commodore 128. The most visible changes from earlier versions of SUPERMON are: --decimal or binary input allowed; --disk status and commands (@); --looser (easier) syntax. NUMBER CONVERSION <$2000> $2000 +8192 &20000 %10000000000000 In the above example the user has asked for the numeric equivalents to hexadecimal 2000. The reply shows the value in hex ($), in decimal (+), in octal (&) and in binary (%). The user could ask for a number to be converted from any of these bases by giving the appropriate prefix. IMPORTANT NOTE -- At any time in the following text, you may enter any number in any base and conversion will be done for you. Example: Will cause a memory display from decimal address 4096. In the display, the hex address ($1000) will be shown. Similarly, <+2048 lda#%10000000> Will be converted to assemble: "a $0400 lda #$80" If you don't give a prefix, the monitor will assume hexadecimal. REGISTER DISPLAY pc sr ac xr yr sp ; 0000 01 02 03 04 05 Displays the register values saved when SUPERMON+ was entered. Values may be changed by typing over the display followed by a return character. pc - program counter sr - status register ac, xr, yr - a, x, and y registers sp - stack pointer >0200 4d 20 32 30 30 20 32 30: m 200 20 >0208 39 00 00 04 00 04 00 04: 9....... Display memory from 0200 hex to 0209 hex. Display is in lines of 8, so addresses $200 to $20f are shown. If only one address is used then 12 lines (96 locations) will be shown. If no address is given display will go from the last address. Equivalent ASCII characters are shown in reverse at the right. Values are changed by typing over the display followed by a return character. EXIT TO BASIC Return to BASIC READY mode. When you wish to return to SUPERMON+, command "SYS 8". SIMPLE ASSEMBLER (changes to:) a 2000 a9 12 lda #$12 a 2002 ..next instruction In the above example the user started assembly at 2000 hex. The first instruction was load a register with immediate 18 decimal. In following lines the user need not type the "a" and address. The simple assembler prompts with the next address. To exit the assembler type a return after the the address prompt. Previous lines may be changed by typing over the right hand part. . 2000 a9 12 lda #$12 . 2002 9d 00 80 sta $8000,x Disassembles instructions from 2000 to 2004 hex. If one address is given, 20 bytes will be disassembled. If no address, start from the last used address. Code may be reassembled by moving the cursor back and typing over the right hand part. FILL MEMORY fills the memory from 1000 hex to 1100 hex with the byte ff hex. GO (RUN) Go to address 1000 hex and begin running code. If no address is given, the address from the register is used. JUMP (SUBROUTINE) Call address 1000 hex and begin running code. Return to the monitor. HUNT MEMORY Hunt thru memory from c000 hex to d000 hex for the ascii string "read" and print the address where it is found. A maximum of 32 characters may be used. Hunt memory from c000 hex to d000 hex for the sequence of bytes 20 d2 ff and print the address. A maximum of 32 bytes may be used. FILE HANDLING LOAD Load any program from cassette #1. Load from cassette #1 the program named "ram test". Load from disk (device 8) the program named "ram test". This command leaves basic pointers unchanged. SAVE Save to cassette #1 memory from 0800 hex up to but not including 0c80 hex and name it "program name". Save to disk drive #0 memory from 1200 hex up to but not including 1f50 hex and name it "program name". TRANSFER MEMORY Transfer memory in the range 1000 hex to 1100 hex and start storing it at address 5000 hex. COMPARE MEMORY Compare memory in the range 1000 hex to 1100 hex with memory starting at address 5000 hex. DISK OPERATIONS CHECK DISK <@> Get disk status message <@9> Get disk unit 9 status message <@,$0> Get drive 0 directory <@,s0:temp> Scratch file 'temp' from disk OUTPUT TO PRINTER Call SUPERMON+ from basic with: All commands will go the printer. When complete, return to basic with "x" and command: SUMMARY $ , + , & , % number conversion g go (run) j jump (subroutine) l load from tape or disk m memory display r register display s save to tape or disk x exit to basic a simple assembler d disassembler f fill memory h hunt memory t transfer memory c compare memory @ disk status/command Supermon will load itself into the top of memory...wherever that happens to be on your machine. Be sure to note the SYS command which links SUPERMON to the Commodore. It may be used to reconnect the monitor if it is accidentally disconnected by use of the run-stop/restore keys.
