Help With Array Operations in AWK
I have two files

file1
[
Code:
            A 2 4 6 8
            B 1 3 5 7
            C 1 3 5 7
            D 1 3 5 7
            E 1 3 5 7

file2
Code:
             C D E F G
           H I J  K L

I need to add field 1 of file1 to both field 2s of file2 and repeat the same on all the rows in file 1...... so the output should be

A+D
A+I
B+D
B+I.......ect

The code below is what I have, but there has to be a better way. You see I have to repeat the same command 5 times to account for the 5 rows in file1

Where: CONG[i,j] is a multideminsonal array of file1 and SA[i,j] is a multi-dimensional array of file2


Code:
awk ' { for (j=1;j<=NF;j++) {
         CONG[NR,j]=$j
                             }
        {getline < "'$SA'"}  { for (j=1;j<=NF;j++) {
                                 SA[NR,j]=$j      }
                             }
       {for (i=1;i<=NR;i++) {print SA[i,1],SA[i,2],CONG[1,2],CONG[1,5],CONG[1,5] + SA[i,2]}}
       {for (i=1;i<=NR;i++) {print SA[i,1],SA[i,2],CONG[2,2],CONG[2,5],CONG[2,5] + SA[i,2]}}
       {for (i=1;i<=NR;i++) {print SA[i,1],SA[i,2],CONG[3,2],CONG[3,5],CONG[3,5] + SA[i,2]}}
       {for (i=1;i<=NR;i++) {print SA[i,1],SA[i,2],CONG[4,2],CONG[4,5],CONG[4,5] + SA[i,2]}}
       {for (i=1;i<=NR;i++) {print SA[i,1],SA[i,2],CONG[5,2],CONG[5,5],CONG[5,5] + SA[i,2]}}
      }' | sort -u |

Thanks

Don't quite understand the desired output, but... something to start with:
Code:
nawk '
FNR==NR {f1[FNR]=$2;next}
{ for(i=1; i in f1; i++) print $1 "+" f1[i]}' file2 file1

Thanks vgersh9, I'll try this out.

In short, I want to add/subtract the first field in file1 with every field 2 in file2, and repeat the process for every row in file1

A+D
A+I
B+D
B+I
C+D
C+I
D+D
D+I
E+D
E+I
