st: displaying summation of a variable

["b. water" <barleywater@hotmail.com>]

dear statalisters,

Stata 8.2 Window XP Pro SP2,

i have a variable 'total', which represents population (no. of persons) per 
observation. what i wanted is quite simple - simply to sum(total) to give 
the overall total no. of person in the dataset. so i did egen 
sumpopn=sum(total), which created a variable sumpopn filled with a constant 
equalling the overall sum, then took a peek at it using display sumpopn. it 
does the job... but is there a shorter way of doing this without -egen- ing 
a new variable (i know i can always -drop sumpopn- later)?

regards,
bw
