Thanks much for responding.  My responses to your comments:

Your right on the output... I cut out the stuff I tried but did not work in the 
program for clarity.

And 2 your are also right that it did not come from PDKsh.... I actually tried 
to envoke PDKsh by putting #!/bin/PDKsh on line 1 of test1 and test2 but all I 
got was an error msg (: bad interpreter: No such file or directory).

I have come to realize that there is more than 1 implementation of ksh.  The 
syntax I used in my example is exactly what I use on my hp unix workstation and 
it works fine on the hp.  I did try to export individual elements like you 
suggest with no luck.

I did find in my installation in the cygwin/bin dir a file ksh.exe which is 
what I assume it was running.  Guess that is not pdksh.

My own IT people do not know what version of cygwin I am using (I am not 
laughing!)  I will try to find out more info on this.  I think we are using 
redhat, but will dig deeper.  Thanks

Your last comment - are you saying I may not be able to export my array data to 
later processes or script files ?

Thanks
Bob
