Set obs with scientific notation

[Trevor Williams]

clear
set obs 1000

Works. But:

clear
set obs 1e3

returns the error "observation number out of range."
I want to set the number of observations to, say, 100 million or 1 billion without having to count all the zeros.

You need a force evaluation:

clear
set obs `=1e3'

[Nick Cox]

. scalar nobs = 1e8

. set obs `=nobs'

Brilliant. Thank you!
