Option -mz: Select Output Format MZ
Option -mz selects output format MZ. This will write a binary in DOS MZ format. The module's default file extension will be changed from .OBJ to .EXE. All symbols in the module must resolve internally, no externals are allowed. Some values in the "MZ" header can be adjusted by directive OPTION MZ (see below).As in all binary formats, the listing will contain a binary map; see Binary Output Format for more details.
Chapter Output Formats lists all available output formats.
