Hi aus9,

In Your script You are assigning variables inside the here-file. This is funny and tricky but may cause brain damage )

--- Code: ---tc@box:~$ cat aaa
cat > bbb << EOF2
N=abc
cat > $N << EOF
ls
EOF
EOF2
tc@box:~$ . ./aaa
tc@box:~$ cat bbb
N=abc
cat >  << EOF
ls
EOF

--- End code ---

Can You rewrite Your script at least to move variables definitions out of the here-file fragment?
