'make run-cosmos' now boots a machine with Asm.sbx on the disk and two
source files to point it at, so the thing can be watched working rather
than only tested:
> load Asm.sbx
> run hello.asm
wrote hello.bin: program 17, data 14, labels 2
> run strings.asm
wrote strings.bin: program 62, data 88, labels 4
Both come out byte for byte identical to the C assembler's, and both run.
hello.asm and testPrograms/stringKeyword.asm are the two single-file
programs with no #Include, which is what the native assembler handles so
far; strings.asm is the second because it has a subroutine and a label
used before it is defined, so it exercises a forward reference that
hello.asm does not.
The assembler builds from its own directory rather than from Apps/,
because it is not one file. Its pieces are found beside it without being
told, since an include is looked for next to the file that asked for it
before anywhere else; only services.asm needs the include path.
ALSO A CORRECTION. Asm.asm's header, its usage message and the Assembler
Manual all said 'run Asm.sbx hello.asm'. That is the convention we talked
about wanting later, not the one this shell has: load and run are separate
commands, so the whole rest of the run line is the argument and that form
asks for a file called "Asm.sbx hello.asm". All three now say load first.
