CLtL2 Reference 

macro IN-PACKAGE : (name) 

function INTERN : (string)
Finds and returns a symbol whose name is STRING. INTERN will create the symbol if it does not exist. Unlike Common LISP intern, the SubL version does not allow an argument to specify the package, since SubL does not support packages. 

function FIND-SYMBOL : (string)
Finds and returns a symbol whose name is STRING. Unlike Common LISP FIND-SYMBOL, the SubL version does not allow an argument to specify the package, since SubL does not support packages.
