UDF help (1.9.4)

[Bernd Becker]

Hello.

I managed to build a udf  to sort data but cannot quite make it do what
I want.

tmean is a 1-d vector of temperature values, no missing data, nice.

What are the important aspects of calling a udf this way

   'd sort(tmean, first)'

that works and this way,

   'define a=sort(tmean,first)'

that does not work.

I want to access the values of a, those that are plotted successfully in
the first case for further processing.

And I want to avoid to write the data out and read them back in!

How can that be achieved?
Are there better ways to do this in grads2?

As usual many thanks!

Bernd.
