On string concepts and their implementation
School of Computing Studies, University of East Anglia, Norwich, UK
A model is described for string handling, distinguishing between fixed length vectors of characters and strings which vary in length under string operations. String processing facilities in PL/I and ALGOL 68-R are considered with particular reference to variability of length of segments of strings. Operators and procedures are defined in ALGOL 68-R for processing both fixed and variable length strings.
