The single quotes were bombing, I did "'blah'" , but I got a parse error

but I figured out a work around --=20
I just store the drive letter and drive dir and seperate props,=20
then I can do replace=3D"${driveletter}\\\\${actualldir}".....


The other workaround I found was to do 2 replaces, the 1st one writes
the prop value without the slashes, then on the 2nd replace I add the
slashes in, but it's not a=20
specific as I would like it too be...

No, the single quotes are treated as normal characters.
