Digitalk will make available patches to its products which
are fixes to those products in the interim between new
releases.  These patches contain fixes to software and
documentation. 
 
The files comprising a patch are compressed into a .zip
(or for Mac a .sit) file.  The file will be named according
to the following format: nnvvpp.zip, where nn is a two
letter mnemonic for  the product (vd = V DOS, v2 = V 286,
vm = V Mac, vp = V PM, vw = V Windows), vv is the version 
of the product for which the patch applies (10 = 1.0,
11 = 1.1, 12 = 1.2, etc.). and pp is the number of 
the patch itself.  VW1002.ZIP indicates the patch applies
to Smalltalk/V Win 1.0, and it is the second  patch that
applies to this version of the this product.  The latest
patch  for a given product/version shall either incorporate
or supercede all previous patches for that product/version,
you need only be concerned about obtaining/installing a single
patch to bring your system up to date.
