Error in parsing the levelsof command on Linux, Stata 18

[Ilya Bolotov]

There seems to be an error in parsing the levelsof command with if in Stata 18 SE on Linux, consult the screenshot.
The same command works well on other systems.

This code (from StataCorp) will not work on any OS. The if statement (if ("`if'`in'" != "")) should have been in compound quotes, and I believe StataCorp has fixed this in an updated version.

What do you get from

which levelsof

should be

path\ado\base\l\levelsof.ado
*! version 3.2.3  16aug2023

If not, type

update query

and follow the instructions.

Dear Daniel,

the code

(if ("`if'`in'" != ""))

is the output of the trace, not my creation. So, you yourself confirm that there is a bug. No worries, I'll write it in a different way.

Thank you for the quick response.

Yes, it is a bug. Yes, it is from StataCorp (as I have noted). You do no not need to rewrite; you need to update your Stata.
