-joinby- requires you to specify the -using- dataset.
In your sample code you have: joinby x, using a.dta

Subject: st: -joinby- doesn't recognize -using- dataset
Hello Statalist folks,
I created the sample code below which successfully runs a -joinby-
operation on a test dataset.
However, when I invoke the same -joinby- command:
. joinby group
using my live datasets, I am met with error message:
. joinby group
using required
r(100);
I have confirmed that directories and filenames are correctly specified.
clear
set obs 3
gen a = _n
gen group="x"
list
save a, replace
clear
set obs 3
gen b="a"
replace b="b" in 2
replace b="c" in 3
gen group="x"
list
joinby group using a.dta
sort a b
list a b group
