Hello again :-) ,
This script is very much a work in progress, and I think only the second time I have tried classes. What I expected it to do was to at least print 'hi there' so I know its alive, then dump some status info to my log program. It does zip, executes OK but no output.
I just know you guys are going to tell me I have missed a () or . somewhere
Any help gratefully appreciated Dave
