st: copying a string variable to all rows within a group

Dear All,
If I have a numeric variable "oldvar" which appears on only the first row of a set of rows defined by a group variable "groupvar" (rest of oldvar rows are blank), it is easy enough to copy oldvar down all rows within groupvar:
bysort groupvar: egen newvar=max(oldvar) // can equally use =min(oldvar) as there is only 1 value of oldvar.
How might I do the same to copy a string oldvar to all rows - again it only appears once within the group, but not necessarily on the first row.
