There's a file with data (time markers, pressure, bubble diameter, pump volume) which is read and plotted on the screen. Upper and lower envelope waveforms are calculated and plotted. A differential pressure waveform is calculated and plotted, and used, with the dynamic diameter data, to calculate - you guessed it - the dynamic surface tension of a lipid. The whole works is saved as a new data file, ready to be recalled.

There's no law against using globals. If you need 'em, use 'em.

As Max noted a while back, "Anyone ever look at all the globals in the FBtoC source?"   :-)
