David,
The following method works for me (I normally use the C shell):
#---cut here---
#!/bin/csh -f
# Sample script to execute IDL in batch mode
# Create IDL run script
echo "print, 'Hello world'" > runidl
echo "exit" >> runidl
# Run IDL
/usr/local/bin/idl runidl >& runidl.out
#---cut here---
You may need to adjust the last line if IDL is installed in a
non-default directory.
Cheers,
Liam.
