The problem is in your closing quotes for your local macro variables.
I adjusted your code to run with the auto dataset as follows:

sysuse auto, clear
sum rep78
local minyear = r(min)
local maxyear = r(max)
local yrdiff = `maxyear' - `minyear' // T-1
di `yrdiff'


Before I corrected the quotes and using your copied code I could
replicate your error in Stata10/SE for windows.

Best,
Alan
