Dear John,
I've noticed the same problem w/ ModelSim EE V5.3c. It's really a shame!
In my particular version of ModelSim, the only real problem with the
generated Tcl script is a few misplaced spaces. By removing the excess
spaces, I can get ModelSim to read the script back in again.
$ perl -pi -e 's/ , /,/g;s/ }}/}}/' tcl_script
This little trick has saved me many, many hours of hair pulling!
