Generating a cdf namelist gives errors

[thomaswilder]

I am running cdfnamelist -p to generate a template namelist as some of my variable names are different to the prescribed names set. Running this command results in a file PrintCdfNames.namlist with the contents

 ! Tue Sep 12 16:03:34 2023
 ! Namelist automatically generated by PrintCdfNames 
 ! Do not edit without changing its name ... 
 ! ------------------------------------------

and a .err file like

At line 348 of file modcdfnames.F90 (unit = 3, file = 'PrintCdfNames.namlist')
Fortran runtime error: End of record

Could anyone advise how I should generate a template namelist, and what I may be doing wrong?
