The command-line tool exe2bin is a post-compilation utility program available on MS-DOS and other operating systems.


Overview

Early compilers and linkers for the MS-DOS platform could not produce a COM file executable directly. Instead, the compilers would output an EXE-format file with relocation information. If all 8086 segments were set to be identical in such an EXE file (i.e. the "tiny" memory model was used), then exe2bin could convert it to a COM file. exe2bin could also be used to convert compiled code to make it suitable to be embedded in ROM as part of

Availability

The command was included in MS/DOS versions 1 thru 3.1 as part of a standard distribution. For version 3.2, among the changes were the version included did not permit itself to run on any version except 3.2. For the next version, 3.3, there was no EXE2BIN on the DOS disk. "Instead, IBM sells the program separately, at an extra cost, with the DOS Technical Reference." IBM also added code to check the version. ''PC Magazine'' published a workaround: just patch it to work with 3.2 or higher. One way or the other, it was no longer available for the base price after 3.2; for version 6 it was on what was called the Supplemental Disk. The program was also distributed with many
