Converts an .exe (executable) file, specified by source pathname,
to .com file format (binary format). EXE2BIN is an advanced
command, recommended for experienced users only. The source
file must be in valid .exe format produced by the linker. The res-
ident, or actual code and data part of the file, must be less than
64K. There must be no STACK segment.
Parameters
source pathname specifies the file to be converted. If you do not
include an extension in the source pathname, the extension
defaults to .exe. .
target pathname specifies a file to receive the converted program
file. If you omit the drive, EXE2BIN uses the drive specified in
the source pathname. If you omit the extension, it gives the new
file the extension .bin. If you omit the entire target pathname,
EXE2BN uses the source pathname.
Notes and Suggestions
• Converting executable files to binary format saves space and
speeds program loading. Two kinds of conversions are possible,
depending on whether the initial CS:IP (Code Seg-
ment:Instruction Pointer) is specified in the .exe file.
• If CS:IP is not specified, EXE2BIN assumes a pure binary
conversion. If segment fixups are necessary (the program con-
tains instructions requiring segment relocation), EXE2BIN
prompts for the fixup value. This value is the absolute seg-
ment at which the program is to be loaded.
In a pure binary conversion, the resulting program is usable
only when loaded at the absolute memory address specified by
a user application. The command processor cannot properly
load the program.
• If CS:IP is specified as OOOO:IOOR, EXE2BIN assumes the file
is to be run as a .com file with the location pointer set at
IOOR by the assembler statement ORG. It deletes the first
IOOR bytes of the file. It allows no segment fixups, as .com
files must be segment relocatable.
