Version 2.0
 - many changes so as to compile for PowerPC
 - uses new Apple floating point so internal calculations now in double precision rather than extended
 - makes better use of System 7 features and conformance to Apples guidelines
 - remembers which type of Report file you used last
 - wider and better Define dialog
 - fixed bug which caused large (>8000 points) graphs to not display
 - 68K version now requires at least System 7
Version 1.6
 - changed Record to Report
 - Report can be saved as either Text or RTF format (Warning: there appears to bug in the Claris RTF translator 1.1v3(x22) which came with the upgrade from 4.0v1 to 4.0v2,3, or 4 - previous versions work fine)
 - Add . - add a single term to model
 - display CORR in blocks of 6 instead of 8 to allow dispaly on standard paper width
 - if Binomial model check for value of binomialn equal to zero and display error message if this occurs
 - changed p-values in Estimates display so that t distribution is used when scale is estimated and normal distribution when scale is fixed
