Disassembled Program Listings contd.
Example:
> MD2 1000 10;DI < CR> disassembled output to Host
Remember, a disassembled source line may not look identical to the entered statement
or instruction, for example this will occur if:
(a) the default data format for constants is decimal; hex constants are returned
in decimal notation.
(b) various instruction types are not always separated; CMP and CMPI
(c) PC relative operations are indicated as absolute address references; BRA.S as
BRA.S $2000.
Saving Programs
If, after a program has been created and tested, a permanent copy is desired for docu-
mentation purposes, or to avoid re-entry the next time it is to be executed, it can be
saved. The methods available will depend upon the system hardware.
Upload to a Host
Programs can be saved by uploading to a host computer via Port 2 of the PME 68-1B.
Once a program has been sent, it can be saved on the hosts mass storage media. Up-
loading to a host requires a program in the host to input the S-records from the RS232C
port and save them either in RAM or directly onto the mass storage media (see para.
6.15 for S-record format).
Uploading to a host is another method of saving programs and it also uses the DUMP
command. A file is usually uploaded through Port 2. In order to upload successfully, the
host must contain a program to input S-records from the RS-232C port and save them.
The PME 68-1B CPU board can upload to any host which has an RS-232C port and the
required program.
Download from a Host
Files must be in S-record format. As well as retrieval of programs created using the resi-
dent assembler/disassembler, the LOAD command is a handy tool for loading 68000
language programs created using the hosts resident or cross assembler. Such assemblers
currently exist for many potential host computers. This can be achieved by performing
the following sequence:
