Thank you for your concern Svend. I had leapt to the assumption that my problem was with _drop_. With some embarassment, I can now report that I had earlier renamed the "missing" age variable to dxage...
My apologies.

I have a dataset that includes two variables:
age
agecat

I'm puzzled as to why
. drop age
will drop both! Should it behave this way?

===================================================================

I can not reproduce your finding which certainly is disturbing.
I did:

. clear
. set varabbrev on
. set obs 1
. gen age=1
. gen agecat=1
. list , clean

age agecat 1. 1 1
. drop age
. list , clean

agecat 1. 1
So, even if -varabbrev- is on, -drop age- did not drop -agecat-.
