Need help with reading until one field in multiple records all go to zero in AWK

I am developing a script to automate Global Mirroring on IBM DS8100's.
Part of the process is to establish a global copy and wait until the
paired LUN's Out of Sync tracks goes to zero. I can issue a command to
display the ouput and am trying to use AWK to read the appropriate
field. I am simulating the command output (since I can't do it live) by
capturing the output to a file and then reading the file. My problem is
I haven't figured out how to use getline to read the file multiple
times. Here is what I'm attempting:

while ( EndofRout > 0 ) {
NR = 1
while ( (getline < "/tmp/output.orig") > 0 ) {
OutSyncTrack[NR] = $7
NR++
} # end of while getline to build OutSyncTrack array
#
#
for ( x = 1; x <= NR; ++x ) {
EndofRout = 0
print "EndofRout is " EndofRout
if ( OutSyncTrack[x] != 0 )
EndofRout = 1
continue
}
}

The field $7 starts off as a high number then gradually goes to zero. I
can simulate this by editing the file, but my problem is that it is
only reading the file once even though $7 is not zero. Any help will be
greatly appreciated. Thanks in advance.

You just touched my sweet spot :))
Don't rule out Fujitsu Siemens' BS2000/OSD.
Same capabilities, reliability and security, but much more
structured, and easier and less expensive to administrate.
Ok, I'm biased, I'm the BOFH of one of those systems.
My humble apologies for this OT posting.
