Add "basic" output format Add "basic" output format. This outputs the code in the form of a Basic program that installs the assembled output. If an execution address is provided to the END pseudo operation, it will transfer control there using the Basic EXEC command. Thanks to Tim Lindner <tlindner@macmess.org> for the original patch. I used it mostly as is except for a couple of minor fixes for coding style and removing a variable declaration from inside a for() statement for portability reasons.
