missing list file

[Christian Struck <Christian.Struck@xxxxxxxxxxxxxxx>]

Dear TRNSYS user,

I am fairly new to the software and was just following the solar water
heating example 1.
I created the model and tried to run but it brings up an error message and
refers myself to the listing file.
For some strange reason TRNSYS does not create a list file at all?!

I might have made a fundamental mistake and I am not sure what else to
check! Your input will be appreciated!

Many thanks for your effort in advance!

Christian
