v:preserve
Data: aq-
Addr: -
Float: -
Make a copy of the value at the address, then run the quote. Once the quote completes, restore the address to the specified value.
Class: class:word | Namespace: v | Interface Layer: all
------------------------------------------------------------------------
v:update
Data: aq-
Addr: -
Float: -
Fetch a value from the specified address, then run the quotation with this value on the stack. Afterwards, store the returned value at the original address.

------------------------------------------------------------------------
var
Data: s-
Addr: -
Float: -
Create a variable. The variable is initialized to 0.
Class: class:word | Namespace: global | Interface Layer: all
Example #1:
'Base var
------------------------------------------------------------------------
var-n
Data: ns-
Addr: -
Float: -
Create a variable with the specified initial value.
Class: class:word | Namespace: global | Interface Layer: all
Example #1:
#10 'Base var-n
------------------------------------------------------------------------
while
Data: q-
Addr: -
Float: -
Execute quote repeatedly while the quote returns a `TRUE` value. The quote should return a flag of either `TRUE` or `FALSE`, though `while` will treat any non-zero value as `TRUE`.

Example #1:
#10 [ dup n:put nl n:dec dup n:-zero? ] while
------------------------------------------------------------------------
xor
Data: mn-o
Addr: -
Float: -
Perform a bitwise XOR operation.
Class: class:primitive | Namespace: global | Interface Layer: all
------------------------------------------------------------------------
{
Data: -
Addr: -
Float: -
Begin an array. This is intended to make creating arrays a bit cleaner than using a quotation and `a:counted-results`.
Class: class:word | Namespace: global | Interface Layer: all
------------------------------------------------------------------------
{{
Data: -
Addr: -
Float: -
Begin a lexically scoped area.
Class: class:word | Namespace: global | Interface Layer: all
------------------------------------------------------------------------
}
Data: -a
Addr: -
Float: -
Complete an array begun by `{`. Returns a pointer to the data.
Class: class:word | Namespace: global | Interface Layer: all
------------------------------------------------------------------------
}}
Data: -
Addr: -
Float: -
End a lexically scoped area. This will hide any headers between `{{` and `---reveal---`, leaving only headers between `---reveal---` and the `}}` visible.
