Ambigious tempfile error

[Konrad Zdeb]

Colleagues,

I'm importaing some data that I would like to store some data via the tempfile in order to merge with the master data set that I'm working on. The extract of the code is available below:

/* Source the postcode latitude and longitude data */
preserve
copy "http://www.freemaptools.com/download/full-postcodes/postcodes.zip" ///
    postcodes.zip, replace
unzipfile postcodes.zip, replace
import delimited using "postcodes.csv", clear varnames(1)
clonevar PostalCode = postcode
tempfile "`temp2'"
save "`temp2'"
restore
merge m:1 PostalCode using "`temp2'", keepusing(latitude longitude) ///
    generate(mrg_pclatlon) keep(match)

As illustrated above Stata returns an error when attempting to process the tempfile command:

. /* Source the postcode latitude and longitude data */
. preserve

. copy "http://www.freemaptools.com/download/full-postcodes/postcodes.zip" ///
>     postcodes.zip, replace

. unzipfile postcodes.zip, replace
   inflating: postcodes.csv
successfully unzipped postcodes.zip to current directory

. import delimited using "postcodes.csv", clear varnames(1)
(4 vars, 1703528 obs)

. clonevar PostalCode = postcode

. tempfile "`temp2'"
_" invalid name
r(198);

end of do-file

---

Naturally, it should be:

tempfile temp2
save "`temp2'"

I would delete this post but this option does not appear to be available.
