Yes. See -help varlist- for so-called wildcards. They work with suffixes too,

. sysuse auto
(1978 Automobile Data)

. ds
make          rep78         weight        displacement
price         headroom      length        gear_ratio
mpg           trunk         turn          foreign

. ds *t
weight        displacement
