You need the function _substr()_

local first=substr("hey",1,1)
local second=substr("hey",2,1)
di "`first'"
di "`second'"

See help functions  ->  string functions

Hi all,

Does anybody knows how to extract a substring of an arbitrary string 
in order to place it into a macro?

More specifically, suppose i have a string "hey". I want the local
macro `first' to contain the string "h".

Can anybody recommend a way to do it?

In principle the macro extended function "piece" should do the trick,
however this function doesn't allow 1 1 (ones) as arguments (there is
a previous posting on this by StataCorp.)

Any help is greatly appreciated,
