Hello
Thanks for reminding me that I need to type di before functions.
In spite of my ignorance of the commandline, the mdy command really did
stop working in the context of a .do script which I have run 1000
times before, and it only worked again after I typed "update all".
This is the exact command, which now you understand why I didn't put in
my original email:
gen age1=floor(( mdy(ivx50193,ivx50192,ivx50195+1900)-mdy(agh48423,15, agh48424+ 1900))/365.25)
This morning, the do script worked. This afternoon, the do script generated
all empty values for age1. All the variables were non-missing.
It only worked again after I did "update all."
So, why did the mdy command disappear on me, and how can I keep commands
from disappearing again?
Janet
