2. Commandline Options
Entering 'JWasm -?' or 'JWasm -h' will make JWasm display the options it understands. A lot of them exist in both Masm and JWasm, but some are valid for JWasm only; OTOH, a few options are missing in JWasm.Options are usually entered via the command line. Additionally, when starting, JWasm will search for environment variable JWASM and handle it similar to the way Masm handles variable ML. Hence it is also possible to enter options via this method.
The options specific to JWasm - and also the options which are handled somewhat differently by JWasm compared to Masm - will be handled in the following chapters.
One major difference should be mentioned here: JWasm does never launch a linker on its own ( which Masm does unless option -c is given ). This makes a few Masm options useless for JWasm, and hence they are not implemented; see Chapter Known Bugs and missing Features for details.
