I'm not sure if I typed it correctly:
awk '{printf s $3; s=FS}END{print ""}' dom1of5.txt dom2of5.txt dom3of5.txt dom4of5.txt
awk: run time error: not enough arguments passed to printf("Oil[%]")
FILENAME="dom1of5.txt" FNR=1 NR=1

Sorry, printf doesn't work like that with some awk versions, try this:
Code:
awk '{printf("%s%s", s, $3);s=FS}END{print ""}' dom1of5.txt dom2of5.txt dom3of5.txt dom4of5.txt

You should use FNR (not NR) to control multiple files.

Code:
awk '{a[FNR]=a[FNR] FS $2;t=(FNR>T)?FNR:t}END {for (i=1;i<=t;i++) print a[i]}'  file1 file2 file3 file4
