I have a program that makes extensive use of Strings with a capital S.

Is there a way to implement any kind of garbage collection or dynamic memory restructuring so that things keep running smoothly with the strings changing size all the time?

From the days of Bill Gates and Ric Weiland BASIC port from 8080 to 6502, garbage collection has been implemented within BASIC itself. I can remember my old PET 2001 4K machine having pregnant pauses during Star Trek. To my knowledge, you will need to supervise your own routines.
