===== Additional variables for HTTP POST multipart/form-data logging =====

The following variables are only supported in HTTP POST multipart/form-data logging.

They must be typed into the "value" field as is, with no other strings/variables around them.

| %ALBUMART | Album art (if available), as binary form data (from v6.3.3) |


===== Additional variables for playlist/advertising import (filename pattern) =====

| %B | Block number |
| %2B | Block number, two digits, leading 0 |
| %3B | Block number, three digits, leading 0 |
| %N | Region number |
| %2N | Region number, two digits, leading 0 |
| %3N | Region number, three digits, leading 0 |


===== FormatDateTime =====

Some variables expect a time format string in Delphi's FormatDateTime notation, see http://www.delphibasics.co.uk/RTL.asp?Name=FormatDateTime 

===== Subsequent items =====

By using ''+'' signs in the variables, you can access the data of the subsequent (next) items in the playlist.

For example ''%+a'' retrieves the artist of the next item, not the current one, ''%++a'' the artist of the item after the next item, and so on.

For performance reasons, the number of items considered/available is limited to 3 by default. You can adjust this value through a manual setting in mAirList.ini:

  [Options]
  NextLoggingLimit=10
  
Please note that this limit applies to the **overall** number of subsequent items available for logging, before any possible item type filtering. So if you want to log e.g. the next 3 "Music" items, but there are times when there are 4 non-music items in between (jingles, news, advertising, etc.), you must set the limit to 7 or higher.
