Another is that whenever a number is expected, expressions, including the ones

with variables in it, work fine.

|

### One-liners
|
||||
|
||||
The `:` character, when not inside a `""` literal, allows you to cram more than
|
||||
one instruction on the same line.
|
||||
|
||||
Things are special with `if`. All commands following a `if` are bound to that
|
||||
`if`'s condition. `if 0 foo:bar` doesn't execute `bar`.
|
||||
|
||||
Another special thing is `goto`. A `goto` followed by `:` will have the commands
|
||||
following the `:` before the goto occurs.
|
||||
|
||||
### Commands
|
||||
|
||||
There are two types of commands: normal and direct-only. The latter can only
|
||||
be invoked in direct mode, not through a code listing.
|
||||
|
||||
`bye`: Direct-only. Quits BASIC
|
||||
|
||||
`list`: Direct-only. Prints all lines in the code listing, prefixing them

with their associated line number.

`if <cond> <cmd>`: If specified condition is true, execute the rest of the

line. Otherwise, do nothing. For example, `if 2>1 print 12` prints `12` and `if
|
||||
2<1 print 12` does nothing. The argument for this command is a "thruth

expression".
|

`while <cond> <cmds>`: As long as specified condition is true, execute specified
|

commands repeatedly.
|

`input [<prompt>]`: Prompts the user for a numerical value and puts that

value in `A`. The prompted value is evaluated as an expression and then stored.

By default, the shell initialized itself with a CFS device containing the
|
||||
contents of `cfsin/` at launch (it's packed on the fly). You can specify an
|

alternate CFS device file (it has to be packaed already) through the `-f` flag.
|

|
||||
By default, the shell runs interactively, but you can also pipe contents through
|
||||
stdin instead. The contents will be interpreted exactly as if you had typed it
|
||||
yourself and the result will be spit in stdout (it includes your typed in
|
||||
contents because the Collapse OS console echoes back every character that is
|
||||
sent to it.). This feature is useful for automated tests in `tools/tests/shell`.
