st: Preserve vs Save

[Claude Francoeur <claude.francoeur@hec.ca>]

Hello,

I do not understand the difference between the "preserve" and "save" 
commands. I just started a new project, copied and pasted from an Excel 
sheet into Stata 9 data editor and saved the file as *.dta. Should I 
"preserve" my data?

Thank you,

Claude
