NAME

dis6502 - Disassemble 6502 object code

SYNOPSIS

dis6502 [ -b ] [ -p pfile ] file

DESCRIPTION

Dis6502 disassembles 6502 binary files. Binary formats understood include Atari binary files (L menu command) and boot files. Equate and control files can be included via the -p option to name well known locations and to control the disassembly process. The output includes a cross reference.

The disassembly process is a two pass operation: First the program flow is traced starting with the init and run parameters in the file headers. The dump routine then prints out the information.

The command line options are:

-b: Assume that the file is a boot file, not a load file.
-p pfile: Read in the predefine file pfile. Up to 20 -p options may be included.

Lines in pfile consist of:

lineno name .eq number

.stop number

.trace number

Lineno refers to a decimal number. Number may be a decimal number or may be a hexadecimal number (the first character of the number should be "$"). For example, "$21b5" is the hexadecimal number 21b5. Name is a sequence of numbers and characters starting with a letter. .trace causes the trace process to continue at the address given. .stop causes the trace process to stop at the address given.
