I gave this a shot with a windows batch file (although I am not sure I
am doing it right)

path c:\program files\vim\vim71
path c:\dex tracker
gvim bay-at-night.csd
echo \intsr | gvim
echo \<endin> | gvim
echo :r strings.orc | gvim
pause


and it just pulls up gvim bay-at-night.csd and never does the two
searches or pulls up the file.  I do have a windows version of sh if
that works better.
