Error opening file when apply up < foobar.txt is used non-interactively

[Marius Jøhndal]

If apply up < foobar.txt is used in a script file with the -l or -f switch, foobar.txt is not found. If the same is used interactively, the file is found.

Here is a minimal example:

$ cat a.script
read lexc < a.lexc
up < a.txt
$ cat a.lexc
LEXICON Root
  foobar # ;
$ cat a.txt
foobar
 $ foma -l a.script

foobar

This may be a user error on my part, but this behaviour differs from xfst which works in this case.
