st: -tempvar- not dropped after -save-

["Daniel Muller" <danielix@gmx.net>]

I have a (part of a) small program, where I create -tempvar-s. However,
the -save- keeps these temporary variables in the saved file. What am I
missing here?

---------------
prog def spatsam
	version 8.0
	syntax , Gap(int) Xc(str) Yc(str) SAVing(str) REPLACE
	preserve
	tempvar x y
	gen `x'=`xc'/`gap'
	gen `y'=`yc'/`gap'
	keep if `x'==int(`x') & `y'==int(`y')
	save `saving', `replace'
	restore
end
---------------

Thanks in advance, greetings,
Daniel
