Importing data

Two SAS files for importing data. The files read the files for individual insects, extract the essential elements, and return a single file That has all the insects. The file has three variables: insect number, waveform, and duration. This contains all the information present, and all other variables can be calculated from these numbers. Note that this format avoids the problem with uncertainties regarding a TBF variable. TBF is time from beginning of file. It might be times from the beginning of a behavior or the end of a behavior. Both options work, but invites confusion if different people use different formats.
