DESCRIPTION:

Some commands of eccet manipulate bitfields.
Where this is the case, you can employ bitop commands.
If the data field starts with
| the following value will be ORed to the current value
& the following value will be ANDed with the current value
^ the following value will be XORed with the current value
= or none of the above, the current value is replaced.
If a tilde (~) follows the initial mode selector, the value
is inverted before the operation takes place
