(I solved this, but there were no obvious hits on this group, so i
thought I'd post it for others scratching their heads in the future.)
When you want to write a string array to a netcdf file, you may find
you are getting an error that the dimensions of your variable dont
match what is declared (in ncdf_vardef). You have to declare the
maximum length of your strings as the first dimension of the string
array variable, else it could be ragged. (Which is how you feel after
combing the IDL documentation for clues).
here's the example that saved the day:

thanks, but you should have asked before. No questions - no answers - no
hits.
The reason for this behaviour is that the data is internally stored as
byte array. That makes 2 dimensions.
