Issue with isfilepresent (NCL version 6.1.2)

Dear NCL developers.

The return value from isfilepresent is wrong when using relative paths. In
my
case I am trying to see if a certain file is present in the parent
directory, for e.g
isfilepresent.

An example

 $ touch ../test

ncl 0> print(isfilepresent("../test"))
(0) True
ncl 1> print(isfilepresent("../test2"))
(0) True
ncl 2> exit

The file "../test2" does not really exist. The following from the linux
command line
returns the correct answers.

$ test -f ../test ; echo $?
0

$ test -f ../test2 ; echo $?
1

The function isfilepresent returns correct answers if I use the full path.

Here are the NCL and system details

NCL version 6.1.2

$ uname -a
