First off, please don't hijack an unrelated thread for your questions --
if you have a separate question, please start a new thread.
Secondly, Windows programs (like SAS) don't understand Cygwin symlinks.
Either let SAS know where the real SPLUS lives, or spawn a Cygwin process
that will understand the symlink (e.g., something like

call system('bash -c "splus70 /BATCH c:\\aldi2\\splus_test\\batch.txt
c:\\aldi2\\splus_test\\batch.out c:\\aldi2\\splus_test\\batch.err"');

).
HTH,
