RE: Command line length limit

Hi Mark,

If your concerned with large zip files, a nice freeware split/join 
program with gui interface is name hjsplit.  I forget where I found it 
but if you have trouble I can see if I can find it again.

BTW: gnu-win32 is a mail list.  Anything mailed to gnu-win32 gets copied 
to anyone on the list.
