<P>I tried again to get the 'ls' command to work in Grads 2 without sucess. </P>
<P> </P>
<P>I've beleive your statement earlier about there being some conflict beteween multiple versions of Cygwin to be correct. I just can't seem to figure out where the conflict is occurring. </P>
<P> </P>
<P>I have 3 version of Grads installed (1.8, 1.9 and 2.0) on the workstation. I deleted all reference to Grads from the Path environment variable (and most any other application other than the basic windows directories), and also renamed Autoexec.bat (it had a reference to the old regrid function). Then did a cold reboot. Plugged in the flash drive with grads 2 on it and started Grads from there, but got not response from ! ls <cr>.</P>
<P> </P>
<P>I then renamed the actual top directories of those 3 versions of grads so even if there was some buried reference, the code would not be found. Restarted. Still no luck with the ! ls command. </P>
<P> </P>
<P>Any other suggestions? <BR></P>

<DIV> Because I am always trying to get a relocatable solution I never make use of the Windows registry. The only system change I make (with the user's permission) is to add something to the path.</DIV>
<DIV><BR></DIV>
<DIV> Now, when you start a version of grads cygwin sets aside a chunk of shared memory for the POSIX emulation. Since v1.9 and v2.0 uses different versions o cygwin, running both versions without an intervening reboot could cause problems as these shared memory chunks could be inconsistent. So, in the machine where you are having problems, do a reboot and then try running v2.0 without having run v1.9. Any luck?</DIV>

<P>Hi Arlindo,</P>
<P>Another finding:</P>
<P> </P>
<P>I have both the 1.9 and the 2.0 Grads installtions on 2 different flash drives.</P>
<P> </P>
<P>I went to a computer that has never had Grads installed, plugged in the 1.9 flash drive and fired up grads, then ran</P>
<P>! ls </P>
<P>and sucessfully received a directory listing. </P>
<P> </P>
<P>Did the same thing with the Grads 2.0 flash drive (on the same computer) and also received a directory liating.</P>
<P> </P>
<P>To me that suggests that indeed there is some sort of conflict occurring on the machine that has previous grads installations. </P>
<P> </P>
<P>I went back to the machine that is having problems and pulled wgrib out of the path too (along with all grads path variables). </P>
<P> </P>
<P>Plugged in the 1.9 flashdrive and got a Directory list, but still no luck with the 2.0 flash drive.</P>
<P> </P>
<P>I also have version 1.8 installed on that machine and am thinking that maybe when I installed it I used the installer version instead of the zip installtion, and that maybe some remnants are still lurking in the registry that might be causing a conflict. That's purely a guess though. Not even sure that would make a difference. </P>
<P> </P>
<P>Any other suggestions? <BR><BR></P>

<P>Hi Arlindo,</P>
<P>Interesting.....</P>
<P> </P>
<P>If I start Grads then type in: </P>

<P> </P>
<P>Grads just hangs. No answer set is returned. I presume a directory list should appear. But instead nothing....</P>

<DIV>Hmm... It works OK on my Windows platform. Anybody out there having similar problems on Windows?</DIV>
<DIV><BR></DIV>
<DIV>I wonder if your GrADS v1.9 installation is not conflicting with your GrADS v2. Do you explicitly set any GrADS environment (GADDIR, GASCRP, etc.)? Is the v1.9 bin/ directory on your PATH? Did you use the .exe or .zip version of the superpack? </DIV>
