My puzzle is resolved in this way:
1. [D] describe tells me that I can abbreviate -describe-
by -d-, so I usually do.
2. However, if I do that and say
. d, simple
Stata fires up the program -d- in d.ado on BASE, which
_ignores_ the -simple- option.
I am tempted to regard this as a bug until told what
I am misunderstanding.
This doesn't affect my advice to Daniel except that
describe, simple
foreach x of var * {
codebook `x', compact
tabulate `x'
}
is an alternative (more efficient than my previous).
