Dear Dave,
this is my Hello example
pro test
print,'Hello'
end
IDL> .run test
IDL> save,file='/tmp/test.sav',/routines,/compress
IDL> idl -rt='/tmp/test.sav'
Installation number:
Licensed for use by:
Hello
And as cron job I got an error message
All arguments are good reasons but not for this simple code.
In the past the idl startup sequence and the word "Hello"
was printed into a mail.
Now it looks like idl -rt won't generally not start as cronjob,
because of a problem with <STDIN>. We do have another problem
sometimes with idlde and <STDIN>. May be this gives a hint what
is different to idl5.4.
At the moment I am helping me with a small script which is
piped into an idl session.

Have you got a "READ" statement (as opposed to "READF") in the code? That
would try and read from the command line and (I guess) would cause an error
in a runtime app (that has no command line). Alternatively, you could be
doing an operation (e.g. "FSTAT") on file unit zero which would also cause
problems when switched to RT mode.
Good luck,
Dave
