47464746 purpose of controlling the format of generated code.
47474747 "format" directive followed by the format identifier allows to select the
47484748 output format. This directive should be put at the beginning of the source.
4749 Default output format is a flat binary file, it can also be selected by using
4750 "format binary" directive. This directive can be followed by the "as" keyword
4751 and the quoted string specifying the default file extension for the output
4749 It can always be followed in the same line by the "as" keyword and
4750 a quoted string specifying the default file extension for the output
47524751 file. Unless the output file name was specified from the command line,
47534752 assembler will use this extension when generating the output file.
47544753 "use16" and "use32" directives force the assembler to generate 16-bit or
47554754 32-bit code, omitting the default setting for selected output format. "use64"
47564755 enables generating the code for the long mode of x86-64 processors.
4756 Default output format is a flat binary file, it can also be selected by using
4757 "format binary" directive. When this format is chosen, special symbol "$%" can
4758 be used to get an offset within the output and "$%%" can be used to get the
4759 actual offset in the output file, omitting any undefined data that would be
4760 discarded if the output was ended at this point. Additionally, for this format
4761 "load" and "store" directives allow access to any data within the already
4762 generated output by following "from" or "at" keyword with ":" character and
4763 then an expression specifying the offset within the output.
47574764 Below are described different output formats with the directives specific to
47584765 these formats.
