[ncl-talk] asciiread

[Adam Phillips]

Hi Ed,
First of all, version 6.0.0 is over 5 years old so we highly recommend you
upgrade to the newest version (6.3.0). This is likely not the cause of the
issue though.

As far as I know asciiread does not have a limit on the size of the file or
on the dimensions of the data array.

Does your ascii file contain anything other than float values? Also, what
happens if you read in the data with a (/-1/) as opposed to (/mn,ml/), do
you get all the data?

As always when you respond please include the ncl-talk email list in your
reply.
Adam
