UDF help (1.9.4)

[Davide Sacchetti]

I had a lot of problems in MALLOC, that is, "define variable=..." with
grads 1.9. The situation got much better with opengrads v1.9.0-rc1
also if I still have some "random" and less frequent problem for defined
variables. Then my suggestion is: upgrade to v1.9.0-rc1.
Bye bye
Davide
