This chapter describes the simple binary output module which can be selected with the ‘-Fbin’ option.
This module is written in 2002-2021 by Volker Barthelmann and Frank Wille and is covered by the vasm copyright without modifications.
Use the given symbol <symbol>
as entry point of the program,
for those output format headers which support it. Otherwise this
option will be silently ignored.
Omitting this option will usually define the execution address
to be the same as the load address.
Writes an Atari DOS COM header preceding the output file. It has
a standard header (0xFFFF
), which is followed by any
number of sections. Each section starts with two little-endian
words defining the address of the first and last byte in memory.
Writes an Apple DOS 3.3 binary file header preceding the output file, which consists of a 16-bit start/load address and a 16-bit file length in little-endian order.
Writes a Commodore PRG header preceding the output file, which consists of two bytes in little-endian order, defining the load address of the program.
Writes a Tandy Color Computer machine language file, which has a header with load address and length for each section and is terminated by a trailer with the execution address.
Writes a Dragon DOS header preceding the output file, where the
file type is set to $02
for binary. The load address is
taken from the first section’s start address. This will also be
the execute-address, when not specified otherwise. Refer to
option ‘-exec’.
Writes a machine code file header for Oric-1, Oric-Atmos and compatible systems. It includes the file type and name, as well as the first and last address of the program to load.
Same as ‘-oric-mc’, but sets the auto-execute flag in the header.
This output module outputs the contents of all sections as simple binary data, by default without any header or additional information. When there are multiple sections, they must not overlap. Gaps between sections are filled with zero bytes, when not using a special header format, like Atari COM. Undefined symbols are not allowed.
Some known problems of this module at the moment:
