[amibroker] osTabSort from Osaka Table

["Paul A." <amibroker@xxxxxxxxxxxxx>]

Can one of you Osaka folks please explain the meaning of the many 
parameters listed in the Osaka docs for the osTabSort function?  I see that 
Andrew Perrin gave a very nice code example of using Osaka Tables, in msg 
#50457.

Below is a snippet of Andrew's code from that msg.  What, please, are the 
meanings of the four parameters that Andrew has passed to osTabSort?

My best guesses are:
1) sRank = the ID of the table that Andrew opened and named sRank
2) i = the column number of the sRank table that gets first priority in 
sorting the rows
3) False = sort by descending order instead of the default ascending order
4) True = ?????   I expected here to see a 2nd column number for use as a 
secondary sort key, not the boolean that was used here.

// ----------------------------------
// Sorting rank calculations
// ----------------------------------

k = StartBar;
i = 0;
while (k <= Finishbar)
{
osTabSort(sRank, i, False, True);
RankValue[k] = osTabGet(Rank_No-1, i, sRank);
i = i + 1;
k = k + 1;
}

FWIW, here is a copy of Joe Osaka's documentation for that function:

NUMBER osTabSort( NUMBER tableid, NUMBER Col1, Number Asc1 = TRUE, NUMBER 
Col2 = Null, NUMBER Asc2 = TRUE, NUMBER Col3 = Null, NUMBER Asc3 = TRUE, 
NUMBER Col4 = Null, NUMBER Asc4 = TRUE, NUMBER Col5 = Null, NUMBER Asc5 = 
TRUE )
//  Sorts table by multiple columns (from 1 to 5)
//  numeric columns are sorted numerically, strings are storted 
alphabetically (case insensitive)
