Pedro,

>I need make one report at running time

It's really easy, with the cursor selected:

create cursor x1 ( i1 i, c1 c(10) )
insert into x1 values ( 1, "test" )
create report x1test from x1
report form x1test preview

you can even allow the user to modify report at runtime and they can tweak the layout.
