Required Parameter: <absLine> => <integer>

Optional parameter: <tabname> => <string>

Return value: <integer>

Description: returns the translation from the absolute index in the list of all items to the constrained position (sorted and constrained) of the specified tablename
if no name is specified, returns the first table, if any.

Note: If tables are displayed in a 3-D sprite, there is only one single tablemanager behavior, which may feed several tables displayed as overlays in the 3-D sprite. therefore we may want to refer to the tables by their name. when used on a 2-D sprite you may omit the <tabname> parameter

Example:
put sendSprite(x, #mConvertToConstrained, 5)
-- 2
