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

zcmp

ZDIFF(1)						      General Commands Manual							  ZDIFF(1)

NAME

       zcmp, zdiff - compare compressed files

SYNOPSIS

       zcmp [ cmp_options ] file1 [ file2 ]
       zdiff [ diff_options ] file1 [ file2 ]

DESCRIPTION

       Zcmp  and  zdiff are used to invoke the cmp or the diff program on files compressed via gzip.  All options specified are passed directly to
       cmp or diff.  If only file1 is specified, it is compared to the uncompressed contents of file1.gz.  If two files are specified, their  con-
       tents  (uncompressed  if  necessary)  are  fed to cmp or diff.  The input files are not modified.  The exit status from cmp or diff is pre-
       served.

SEE ALSO

       cmp(1), diff(1), zmore(1), zgrep(1), znew(1), zforce(1), gzip(1), gzexe(1)

BUGS

       Messages from the cmp or diff programs may refer to file names such as "-" instead of to the file names specified.
