Re: st: How do I convert a numeric monthly date into 1jan2000 format for use as an argument to the haver command?

Nick,

You're exactly right about the haver command. It expects date
constants that match the frequency of the data in question. Running:

    haver use PCUP using "haver\USECON.dat", twithin(2012m1,2013m8) clear

works as expected. Aside: I wasn't expecting the display command to
have any side effects; I forgot to remove it when I reduced my do file
to a minimal working example.
