tex is quoting (i.e., not evaluating) the file name.
so tex writes a file literally named "myfile".
try this:
tex (expr, ''myfile);
or this:
apply (tex, [expr, myfile]);
in both cases, the variable myfile is evaluated (yielding the file name).
note: '' in the first example is two single-quote characters.
hope this helps,
