Is it possible to get Axon to print out the entire error message in the terminal?  

For example, when I run fitsExplain() the message returned is limited to 78 characters in the window's terminal.  Yet other commands like read(ahu) will use the entire terminal window.  

here is an example of the truncation: 
 
axon> read(ahu).fitsExplain(G36SingleZoneAhu)
id                                          msg

The shell is going to try to use your terminal width if you have jline installed - see setup. Otherwise it will default to 80. And there is no way to do line wrapping (which would make it impossible to read anyways).

If you really want to see pipe it something like a CSV file:

read(ahu).fitsExplain(G36Vav).ioWriteCsv(`foo.csv`)

Or you can just iterate thru the rows and print them however you like
