This means that userspace applications must be assembled with a proper `.org`,

The `.org`, it is not specified by glue code of the apps themselves. It is

That a userspace is called also means that an application, when finished

By default, apps set their RAM to begin at the end of the binary because in

most cases, these apps will be ran from RAM. If they're ran from ROM, make sure

## Invocation
|
||||||
|
|
||||||
|
`zasm` is invoked with 2 mandatory arguments and an optional one. The mandatory
|
||||||
|
arguments are input blockdev id and output blockdev id. For example, `zasm 0 1`
|
||||||
|
reads source code from blockdev 0, assembles it and spit the result in blockdev
|
||||||
|
1.
|
||||||
|
|
||||||
|
Input blockdev needs to be seek-able, output blockdev doesn't need to (zasm
|
||||||
|
writes in one pass, sequentially.
|
||||||
|
|
||||||
|
The 3rd argument, optional, is the initial `.org` value. It's the high byte of
|
||||||
|
the value. For example, `zasm 0 1 4f` assembles source in blockdev 0 as if it
|
||||||
|
started with the line `.org 0x4f00`. This also means that the initial value of
|
||||||
|
the `@` symbol is `0x4f00`.
