Mode

This argument determines the mode of selecting a set element:

0 Same as mode 1, but executed only once when no last GE-element exist for specified set.

1 Absolute index (or random if index is null)

2 Backwards relative to last element selected by GE-command

3 Forward relative to last element selected by GE-command

4 Log most recent element selected by GE-command

5 Use index of last random draw (parallel mode)

If a relative index is out of range it will be automatically set to the smallest or highest element of the set.

Mode 0 and 4 are special modes to facilitate the use of the GE-command within a loop to initialize and finally record the element selected with the GE-command.
