Hash tables aren't meant to have a sorted order, they are unsorted by nature. You probably are better off with an arraylist for that.
However, you can use the easy work around of writing the contents of the hash table to a temp file, and sorting the temp file with /filter, since a file on the other hand can be sorted easily.
For saving a hash table's contents to a file, you could use /hsave -oi which will save it as an ini file, with items being seperated from data by a $chr(61) aka =
However that will transform [ ] in the hash table items to ~ ~ to evade ambiguity with topics in an .INI file.
Therefore an easy and very fast trick (which works even faster than hsave -oi) is to use the file handling commands to write every item and its according data to a file using a while loop.
Then it is simply a matter of issuing filter on the temp file, and voila, you have the contents of your hash table sorted.
/help /filter
/help /fopen
/help while loops
/help variables
Alternatively you can also write to a hidden window and /filter the window, if you don't feel comfortable with the file handling commands.
