'SOURCE_FILE' is the name of the source file
(you may omit the default `.asx` extension).
Using '-' as 'SOURCE_FILE' makes *xasm* read from standard input.
When invoked without any options, *xasm* assembles 'SOURCE_FILE'
and writes the result to an object file named 'SOURCE_FILE'
with the extension changed to `.obx`.

Sets output file name.
The default is 'SOURCE_FILE' with the extension changed to `.obx`.
Using '-' as 'OBJECT_FILE' makes *xasm* write to standard output.
The default is 'SOURCE_FILE' with the extension changed to `.obx`, or
standard output if standard input was specified as source.
