Shell Programming and Scripting

The easiest way would be for(X in A) B[X]=A[X]

This works because awk, techically, doesn't have three-dimensional arrays. When you do ARR[A,B,C], it jams A, B, and C together into a single string like A SUBSEP B SUBSEP C.

So you can still loop through them all in a single loop. If you want the individual components of X, you can split them apart on SUBSEP ( a special variable which defaults to an odd, nonprinting ASCII character)

Thank you, in my case I think I have to use loop because after each calculation I am storing result in new field

for example

Code:

for(i=1;i<=10;i++)
# Dummy calculation
x=A[1,i,5]+...........A[1,i,7]
B[1,i,1]=x
 {
for(m=1;m<=NF;m++)
B[1,i,m+1]=A[1,i,m]
}
