st: Reshaping data from list form and grouping by one variable

Hello all,
I’m relatively new to STATA and was wondering whether you
could help me. I am trying to construct a dataset of every countries
contiguous borders. I currently have a list of all of the land borders
in the form of:
StateA, StateB
AFG, CHI
AFG, IRA
AFG, PAK
… and so on.
In total there are 618 observations. I want to instead have it so that the
StateA variable has only unique values and all of its relationships are
listed in the following manner:
StateA, StateB1, StateB2, StateB3...
AFG, CHI, IRA, PAK...ALB, GRE, MAC, MTG ...
The most land borders is 15 so it would have to go up to StateB15. I am
unsure if there is a command which would help me to do this and would
much appreciate any assistance that you could provide. If not, I will
have to input it manually. Thanks in advance for your assistance.
Kind regards,
