Thesis (MSc)--University of Stellenbosch, 2006. / ENGLISH ABSTRACT: Program slicing was originally described by Mark Weiser in 1984. He proposed this as a technique to aid in debugging because he conjectured that this is what programmers did naturally when debugging. Here program slicing is applied to an experimental concurrent language called LF. Existing techniques are adapted to accommodate the unique features of the language. / AFRIKAANSE OPSOMMING: Programdeling is oorspronklik deur Mark Weiser beskryf in 1984. Hy het dit voorgestel as ’n tegniek om ontfouting te vergemaklik, want hy het geglo dat dit is wat programmeerders van nature self doen. Programdeling word hier toegepas op ’n eksperimentele gelyklopende taal genaamd LF. Bestaande tegnieke word gewysig om die taal se unieke eienskappe in ag te neem.
