You can do this in one step and cut out the middle macro.
foreach v of var <varlist> {
twoway (scatter `v' xvar, sort), title(Scatter plot for `: variable label `v'')
}
However, in general various problems are foreseeable.
1. No variable label exists.
2. The variable label includes a comma that will be misinterpreted without
binding the title text in double quotes.
3. The variable label includes double quotes that will be misinterpreted without
binding the title text in compound double quotes.
4. The title text will seem long and repetitive.
4. is easy to fix. The others are fixed by this
foreach v of var <varlist> {
local vtext : variable label `v'
if `"`vtext'"' == "" local vtext "`v'"
twoway (scatter `v' xvar, sort), title(`"Scatter plot for `vtext'"')
}
