StList &= { {0,"LV_COLUMN",
 "mask        : uint    : 1 "& 
 "fmt         : int     : 1 "&
 "cx          : int     : 1 "&
 "pszText     : pointer : 1 "&
 "cchTextMax  : int     : 1 "&
 "iSubItem    : int     : 1 "} }

  pszText is a pointer to a zero terminated string.

  The last numbers should be 1 for each member of the
  structure because it is the number of units or ints or pointers.
  If you were describing for example 20 bytes you
  would use something like "data : byte : 20"
