st: inconsistent behavior of -ds-
Caleb said
To illustrate what appears to be inconsistent behavior of -ds-, consider
this dataset with 9 string variables:
. desc
Contains data from uniondemoc82-3.dta
obs: 180
vars: 10
size: 40,500 (99.9% of memory free)
------------------------------------------------------------------------
-------
storage display value
variable name type format label variable label
------------------------------------------------------------------------

union str80 %80s
id int %8.0g
pres1 str20 %20s
treas1 str17 %17s
sect1 str20 %20s
sect2 str16 %16s
st1 str20 %20s
st2 str16 %16s
st3 str11 %11s
vp1 str19 %19s
. ds
union id pres1 treas1 sect1 sect2 st1 st2 st3
vp1
. ds , has(type string)
union pres1 treas1 sect1 sect2 st1 st2 st3 vp1
. ds, has(type 2/8)
. ds , has(type 2/62)
pres1 treas1 sect1 sect2 st1 st2 st3 vp1
. ds , has(type 2/11)
st3
Looks perfectly consistent with -help ds- to me. ds without arguments
-> all variables, ok. ds with type string, all but id, ok. has(type
2/8) is shorthand for str2,...str8, of which you have none, ok. has
(type 2/62) includes all string variables except union, ok. has(type
2/11) includes only st3, ok. So far ds appears to be batting 1.000.
What is inconsistent here?
