[gradsusr] defined variables

[Semyon Grodsky]

Dear experts,
suppose TEMP is a variable of an open file.
I define new variable

TEMPNEW=TEMP

set x 1
set y 1
set z 1
set t 1 last

the following command works OK
d temp(y+0)

but

d tempnew(y+0)

returns error
World coordinates convert to non-integer grid coordinates
Variable = tempnew Dimension = 0

What is wrong?
GRADS 1.94 on LINUX machine

Thanks
