Anyone know if it is possible to declare an array variable in installscript?  If so, can you show me some syntax.  I do not seem to see this functionality in the documentation.

Steve,
         There is a function in installscript called "Resize."  ISWI recognises the command but there is no help on it for some strange reason.  I found it in "Bob Baker's WI Developers guide" p.547.

Here is the example given in the book:

function Foo()

INT nArray();   //Note no initial size give to array

begin

//Size the array to hold 3 values
Resize(nArray, 3);

nArray(0) = 0;
nArray(1) = 1;
nArray(2) = 2;

//display "Value=1"
SprintfBox(INFORMATION, "Script Test", "Value=%d", nArray(1));
end;

"Resize" I presume supports all the basic data types and structures, 2D arrays are not supported i.e. nArray(1)(2);

And be careful not to make your array smaller than your data or you'll lose some (obviously.)

Hope this helps,
Dave.
