WITH

Enable a special behavior for the subsequent instruction.

Opcode	Bytes	Cycles	Form
$01	1	1	`with carry`
$01	1	1	`with euclid`

Control flag	Output
with (WF)	This flag is always `1`.

Notes

Sets the with flag (WF) for the next instruction only. It will be automatically cleared afterwards.
For clarity, the assembly syntax uses with carry or with euclid according to the subsequent instruction, even though they share the same opcode.
If the subsequent instruction is add, subtract, or compare: with carry includes the carry flag (CF) in the calculation. See the instruction documentation for details.
If the subsequent instruction is a divide: with euclid requests Euclidean integer division instead of truncated division. See the instruction documentation for details.
If the subsequent instruction is not one of the documented forms, the behavior is undefined apart from clearing the with flag (WF). Generally it has no effect; however, future versions may introduce additional behavior.
Unlike all other instructions, with does not clear the skip flag (SF). This allows the pair of instructions to be skipped, for example:
```
compare i:0, 3
if zero           # divide only if i:0 equals 3
with euclid
divide i:4, i:8
```
