SortColNames


Unit: SDL_ntabed
Class: TNTabEd
Declaration: [1] procedure SortColNames (Ascending: boolean; LowCol, LowRow, HighCol, HighRow: integer);
[2] procedure SortColNames (Ascending, IgnoreCase: boolean; LowCol, LowRow, HighCol, HighRow: integer);

The method SortColNames sorts the data contained in the range [LowCol,LowRow] to [HighCol,HighRow], the column names, the column attributes, and the decimal place indicators according to the column names. The values outside this range are not affected. The parameter Ascending specifies whether the valus are to be sorted in ascending (TRUE) or descending (FALSE) order. The additional parameter IgnoreCase in version [2] of this method controls whether lower and upper case letters are distinguished.

The sorting is performed by a modified bubble sort (CombSort), which has been reported to be comparable in speed to QuickSort (see also R.Box, S. Lacey, BYTE magazine, April 1991).
