It's not impossible at all. Stata takes literally
what you include between double quotes " ". Evidently 
you had no strings with values like "71600/71699". 

However, it may be that what you want is accomplishable 
by something like  

forval i = 1/4 { 
	replace newvar = 1 if inrange(real(var`i'),71600,71699) 
} 

but like Richard Williams I am not completely clear from your 
examples what exactly you do want.
