Don't thank me too fast :)
I goofed and forgot to put the part that increments n in there.
So, assuming your shell is ksh (yours is for root, maybe not for other 
users)
the above commands need to be this, these will definitely wrap so just be 
aware this is only 2 lines that both start with n=1and you should see how to 
unwrap them:

n=1 ; until [ $n -gt 676 ] do ; echo "::export(${n})=${n}:" >>prc.exp ; 
n=$((n+1)) ; done
n=1 ; until [ $n -gt 676 ] do ; echo "::export(${n})=fieldname(-,${n}):" >> 
prc.exp ; n=$((n+1)) ; done

in plain sh you'd have to use n=`expr $n + 1` instead of n=$((n+1))
