Don't forget that on Windows it might also fail if the file is in use by another application; a lot of Windows apps appear to default to exclusive file access, and the Windows kernel enforces it. (e.g. if I open a ZIP file in 7-Zip and then forget to close the window before running the script to regenerate the file, it fails horribly. Grr.) -- ┌─── dg@cowlark.com ───── http://www.cowlark.com ───── │ │ ⍎'⎕',∊N⍴⊂S←'←⎕←(3=T)⋎M⋏2=T←⊃+/(V⌽"⊂M),(V⊝"M),(V,⌽V)⌽"(V,V←1⎺1)⊝"⊂M)' │ --- Conway's Game Of Life, in one line of APL
