# If $IFS set, but empty,
# then "$*" and "$@" do not echo positional params as expected.

mecho ()       # Echo positional parameters.
{
echo "$1,$2,$3";
}


IFS=""         # Set, but empty.
set a b c      # Positional parameters.

mecho "$*"     # abc,,
mecho $*       # a,b,c

mecho $@       # a,b,c
mecho "$@"     # a,b,c

# The behavior of $* and $@ when $IFS is empty depends
# on whatever Bash or sh version being run.
# It is therefore inadvisable to depend on this "feature" in a script.
