st: import excel needs hardcoded first character

["Feiveson, Alan H. (JSC-SK311)" <alan.h.feiveson@nasa.gov>]

Hello - I am trying to import an excel file with the file name as an argument. 

In the first example below, the first character of the file name is hard-coded as "t", and I supply the rest of the file name as an argument `fn'. The name of my file is "test.xlsx". This works (see below).


args fn listnumber
import excel using d:\docume~1\afeiveso\mydocu~1\excel\t`fn',clear first case(lower)

. run global_list   est.xlsx 1

[ no errors]


Now in the second example, I try to use the entire file name as an argument. This does not work. 


args fn listnumber
import excel using d:\docume~1\afeiveso\mydocu~1\excel\`fn',clear first case(lower)


. run global_list   test.xlsx 1
file d:\docume~1\afeiveso\mydocu~1\excel not found
r(601);



With trace on, it appears that Mata ignores the filename and treats it as missing. Any ideas of what's going on here?

Thanks

Al Feiveson
