Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The DOS MZ executable format is the executable file format used for .EXE files in DOS. The file can be identified by the ASCII string "MZ" or the hexadecimal 4D 5A at the beginning of the file (the "magic number"). "MZ" are the initials of Mark Zbikowski, one of the developers of MS-DOS. The MZ DOS executable file is newer than the COM executable format and differs from it. The DOS executable header contains relocation information, which allows multiple segments to be loaded at arbitrary memory addresses, and it supports executables larger than 64 KiB; however, the format still requires relatively low memory limits. These limits were later bypassed using DOS extenders. The environment of an EXE program run by DOS is found in its Program Segment Prefix.
