Generating variable with several layers

[Erko Jakobson]

I have Q seasonal averages for 27 level separately (Q_lev1 to Q_lev27). For
making the vertical profiles, I have to put them in only one variable Q,
that consists 27 levels, so I can display the profiles:

'set lat 55 90'
'set lon 90'
'set z 1 27'
'd Q'

It should be function like Q(z)=Q_lev'z', but for me it seems, that in Grads
it is not so easy:(


Thank you very much for any advice,
