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'. |
