fitting random regressions


I'm interested into analysing repeated measurements of a progeny test
using a random regression model, with a econd order polynomial. The data
structure in the data file is:

tree mother father block age height
301    1      0      1      1   0.6
301    1      0      1      2   0.9
301    1      0      1      4   1.5
301    1      0      1      6   2.6
302    2      0      1      1   0.5

Reading the data would be:

Fitting random regression
 tree    !P
 mother 198
 father   1
 block   10
 age    height

I haven't manage how to specify the model for including the tree and
block effect as random using a random regression with a second order
polynomial.  From reading the manual I've got the impression I should
use !ASMV for specifying a multivariate analysis with univariate data
presentation and unit for fitting the error. I've tried several
approaches for the analysis but with no success.  I would appreciate
very much any suggestions or comments about the coding for the analysis.

Thanks in advance,
