Yes, that's what I ended up with. I constructed a TStringTable class that does all I need (and more): - insert, add, delete rows/cols - autogrow colcount (with insertrow) - exchange rows/cols - get/set rows/cols - property Cells[ACol, ARow]: string (read/write) It can be found here: http://svn.code.sf.net/p/flyingsheep/code/trunk/MijnLib/stringtable.pp Implementation can probably be faster (I use dumb for loops to move things around, where maybe I could have used move(), but failed and gave up). It does not scale very well (due to numerous setlength() calls), but filling a 1000x1000 TStringTable just cost me 76 ms. A 5000x5000 table however cost me 1248 ms. B.t.w. for testing purposes I tried to set up a 10000x10000 array of array of string, but the program died on me without a sign of a single exception.
