variable for import field number loop

[Scott Nelson]

Is there a way to use a variable to count through the field numbers on 
an import?  Such as

:import new = importfile r=\n f=;

:x(2,.0)="1"

:aa=new(x); gosub dothis; etc


There are hundreds of fields in each line and I would prefer not to do:

if: x eq "1"
then: aa=new(1)

and so on.
