If you do not specify a source file, PPCAsm assembles standard input. In this case, you can press Command-Enter to terminate input. Though ending an assembly source file with a .s suffix is the common file-naming convention, PPCAsm allows any name. For both assembly source file or standard input, PPCAsm produces object files with a .o extension. For standard input, the object file is a.o .
Checks syntax only, without generating an object file.
This option is equivalent to placing the directive name SET value at the beginning of the source file. Omitting the value causes name to have a default value of 1. If the include file in the source code is specified with a full pathname, PPCAsm searches for the file at that location. The current directory. The directory containing the current input file.
