# The following enclosed script does not want to fully process the input data
# file. It correctly executes the operations on the first record, and then dies
# on the second one. My true data file is much longer but this is
# representative and it does fail on a file even as short as this one.
# The failure appears to occur in the declared function add2output. Between the
# steps of incrementing NF by one and setting $NF to the passed variable
# the passed variable appears to vanish (i.e. NF does go from 68 to 69
# and before incrementing it "variable" equals what it should but after
# "variable" has no value at all.)
#
# The scripts have been developed using nawk on a Sun (where they run fine)
# I have tried gawk there but get a different crash which I have not yet traced
# down. Ideally I would like to keep the script the same so that it would run
# on either gawk or nawk (that way I can step back and forth between laptop and
# workstation.
#
# Any ideas why the laptop installation is having problems?
