The expression Table[Random[Integer, {1, 4}], {Random[Integer, {240, 250}]}] works fine for me. (Win 98 on a compaq 1200 notebook). You probably get into troubles while using a symbol (i) appearing twice, once as a counter for Table, and once for nothing really necessary. If you want to be able to specify the length of your list, you can use genome[i_Integer]:=Table[Random[Integer,{1,4}],{i}] > -----Message d'origine----- > De : joseph [mailto:joseph468 at yahoo.com] > Envoyé : dimanche 18 juin 2000 09:01 > À : mathgroup at smc.vnet.net > Objet : [mg23971] User problem > > > Can anyone help: > I am trying to contstruct a table of random integers > between 1 and 4.
