# With this program, I can read the information from
# Specifications.txt file and display it on a form.
# The user can then update/modify the fields. This is
# all working fine and beeautifully...
#
# I now need to reverse the process and replace the
# adjusted lines of data back into the Specifications.txt
# file. Fortunately, that code has already been
# written .
# What I cannot seem to do is to pull the adjusted
# information from the form into variables, or a
# list/array, so that can be used for the update to the file.
# Suggestions for what to look up to study this
# through will help.
#
# Thank you
