## 2.46 `UNMARK` command

### 2.46.1 Syntax

`UNMark`

### 2.46.2 Purpose

Forget remembered circuit voltages and currents. Undo the ``mark`' command.

### 2.46.3 Comments

Allow time to proceed. It has been held back by the ``mark`' command.

### 2.46.4 Examples

`transient 0 1 .01`
  A transient analysis starting at zero, running until 1 second, with step size .01 seconds. After this run, the clock is at 1 second.
`mark`
  Remember the time, voltages, currents, etc.
`transient`
  Another transient analysis. It continues from 1 second, to 2 seconds. (It spans 1 second, as before.) This command was not affected by the `mark` command.
`transient`
  This will do exactly the same as the last one. From 1 second to 2 seconds. If it were not for `mark`, it would have started from 2 seconds.
`transient 1.5 .001`
  Try again with smaller steps. Again, it starts at 1 second.
`unmark`
  Release the effect of `mark`.
`transient`
  Exactly the same as the last time, as if we didn't `unmark`. (1 to 1.5 seconds.)
`transient`
  This one continues from where the last one left off: at 1.5 seconds. From now on, time will move forward.
