For bubble grading mode and exam bubble printing mode, the tracking of |
| |
the current 'bubble line number' is stored in the %env element |
| |
'form.counter', and is modifed and handled by the following routines. |
| |
|
| |
The value of it is stored in $Apache:lonxml::counter when live and |
| |
stored back to env after done. |

Increments the internal counter environment variable a specified amount |

Optional Arguments: |

$increment - amount to increment by (defaults to 1) |
| |
Also 1 if the value is negative or zero. |
| |
$part_response - A concatenation of the part and response id |
| |
identifying exactly what is being 'answered'. |
