- global-set! GR VALUEprocedure
Sets the value of the element addressed by the global reference GR to VALUE. VALUE will be converted to a string before it is stored. INDEX may be a string, symbol or number and will also be converted to string. If the element doesn't exist yet for G, then it is created. If GR refers to a global, then this is equivalent to global-set! (GR) VALUE).
