Re: ERROR message: input in flex scanner failed

Hi Emma,

Thanks for making the effort to google the message and provide us with more information!

The message is coming from a lower level of coding. I don't think it comes from the way you are calling a specific function or procedure.

Would you be able to provide us with your data and script offline? I'd like to see if I can reproduce it. If so, you can use our ftp to upload your files:

Do you consistently see these weird messages every time you run this script? In my case, it's not consistent, so it's hard to debug.

I printed several statements throughout the script and it came all the way to the end where I printed "DONE". The data I wrote to a file also, by a first glance, looked ok.

Since NCL is based on both Fortran and C and Flex is a lexical analyzer for C/C++ it might have something to do with that.

I don't think it is necessary to describe the whole script, but rather the main steps and what functions I use before this error message shows up. So, after I have been creating monthly climatology (clmMonTLLL ), averaging to monthly profiles (dim_avg_n_Wrap), interpolating to another set of pressure levels (int2p_n_Wrap) and saved the data to a file I get the error message " input in flex scanner failed".
