Global variable

[Boyin Huang]

I failed to define a global variable in Grads 1.85SL11.

Here is the main script
rc = gsfallow("on")
_mc1='i love you'
_mc2='you love me'
'fn.gs '
say _mc1
say _mc2

Here is the sub-script "fn.gs" at the same directory
say _mc1
say _mc2
_mc1='aa'
_mc2='bb'

Here is the output
_mc1
_mc2
i love you
you love me

Obviously, _mc1 and _mc2 defined in the main script have not passed into the
subscript, and those redefined in the subscript have not passed into the
main script either.

What is the problem?
