Annyong haseyo,
I think the " openr, 1, 'c:\user\yong\xy1234.dat' " problem you're
having is
exactly as you described, that \x... is treated as a numeric constant.
This
was changed, I believe in version 3.1 or 3.5 so that it is not treated
this
way, for the convenience of users on DOS machines. (this caused some
problems with people who relied on the \x... notation, but your problem
is
now the reverse!)
If you have any way to upgrade, this will provide the solution, or you
could
try " openr, 1, 'c:\user\yong\' + 'xy1234.dat' " which might work fine
in
some cases. Or in general, '\' + 'x' should be an adequate
replacement.
Cheers,
-Dick
