Jim, thank you so much!  I have implimented the batch files using your code, 
and it works perfectly. Now OpenGEM Release 4 looks for UPDATES and INSTALLS 
as it starts.  Perfect.

OpenGEM Release 4RC1 should be online on the 20th of June.  The final 
release will be one month after that.

Best regards
