For version 3.2, among the changes were the version included did not permit itself to run on any version except 3.2. [4] 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.
This is a list of some binary codes that are (or have been) used to represent text as a sequence of binary digits "0" and "1". Fixed-width binary codes use a set number of bits to represent each character in the text, while in variable-width binary codes, the number of bits may vary from character to character.

Full machine code compatibility would here imply exactly the same layout of interrupt service routines, I/O-ports, hardware registers, counter/timers, external interfaces and so on. For a more complex embedded system using more abstraction layers (sometimes on the border to a general computer, such as a mobile phone), this may be different.
Code is only translated as it is discovered and when possible, and branch instructions are made to point to already translated and saved code (memoization). Dynamic binary translation differs from simple emulation (eliminating the emulator's main read-decode-execute loop—a major performance bottleneck), paying for this by large overhead ...
Offset binary, [1] also referred to as excess-K, [1] excess-N, excess-e, [2] [3] excess code or biased representation, is a method for signed number representation where a signed number n is represented by the bit pattern corresponding to the unsigned number n+K, K being the biasing value or offset.
Some of the more notable uses of balanced-weight codes include biphase mark code uses a 1 of 2 code; 6b/8b encoding uses a 4 of 8 code; the Hadamard code is a of code (except for the zero codeword), the three-of-six code; etc.
