You have a trailing slash in your path macro, but then you manually add
another slash in your save command.

You have a backslash in your fname macro which should be a forward
slash.

It's often helpful to use a display command to check what you are trying
to do in situations like this, i.e.: 

display "`path'/`fname'`i'"

Hi there,

I have following code which let two local macros expand in a file path. 
But after running the looping, the files are saved under C: directly, 
instead of the directory suggested by the code.

local path = "C:/EPI Projects/RRFSS Trends/"
local fname = "Smoking Vehicle\vehicle0"
cd "C:\EPI Projects\RRFSS Trends\data"
forval i = 1/4 {
	insheet cat prop ucl lcl popsize using raw0`i'.txt, clear
	generate year = 200`i'
	save "`path'/`fname'`i'", replace
}

Messages from STATA after running the above code
forval	i	= 1/4 {
2.		insheet cat prop ucl lcl popsize using raw0`i'.txt,
clear
3.		generate year = 200`i'
4.		*save "C:\EPI Projects/RRFSS,	replace
.		save "`path'/`fname'`i'", replace
5. }

(5 vars, 2 obs)
file /1.dta saved
(5 vars, 2 obs)
file /2.dta saved
(5 vars, 2 obs)
file /3.dta saved
(5 vars, 2 obs)
file /4.dta saved

Any one knows what has gone wrong?  Thanks so much!
