#Sorry that was me getting carried away and cut and pasting the wrong thing
#into my email
#
#The real problem seems to be that :
#BEGIN {
#for (i=1;i<10;i++){
# while((getline < "hello.txt")>0){
# print $0
# }
# close("hello.txt")
# }
#}
#works (printing the contents of hello.txt 9 times), where as:-
#
#END{
#for (i=1;i<10;i++){
# while((getline < "hello.txt")>0){
# print $0
# }
# close("hello.txt")
# }
#}
#
#doesn't, (it prints out hello.txt once followed by the iteration numbers
#from 1 to 9).
#The only difference is that one is in the BEGIN block and one in the END
#block.
#
#Sorry about the first post, I'm not a bad awk programmer, just a tired one
#:)
