Thanks posters... yes you've all helped me get lined out.

Yes, I did. But apparently the tools (Uwin) that I have installed
don't work that well in winxp env. At least not the less pager it
uses.
perldoc -f system shows me:
system LIST
system PROGRAM LIST
Does exactly the same thing as "exec LIST", except that a fork
is done first, and the parent process waits for the child pro-
cess to complete. Note that argument processing varies depend-
ing on the number of arguments. If there is more than one
argument in LIST, or if LIST is an array with more than one
value, starts the program given by the first element of the
list with arguments given by the rest of the list. If there is
only one scalar argument, the argument is checked for shell
metacharacters, and if there are any, the entire argument is
passed to the system’s command shell for parsing (this is
"/bin/sh -c" on Unix platforms, but varies on other platforms).
If there are no shell metacharacters in the argument, it is
split into words and passed directly to "execvp", which is more
efficient.
Beginning with v5.6.0, Perl will attempt to flush all files
opened for output before any operation that may do a fork, but
this may not be supported on some platforms (see perlport).
And no amount of space bar pressing or down arrow will show any more.
Its kind of funny because I remembered you had posted something like
this in another thread I started a while back. I went looking for it
but didn't turn it up. Then when I saw the manpage I thought maybe
I'd confused your post with something else.
I see now that I can get the rest of the manpage with Ctrl-f ..
Thanks for the heads up.

Yes, much nicer for my usage .... thanks.
Does perl also have some compression module? My script uses tar but
I'm having trouble because of the win habit of using spaces in file
names.
In fact, on that problem.... is there some sort of standard way that
perl handles that problem on windows? Maybe some specialized module
or etc?
