....has been developed and integrated with the storage allocation mechanisms of different store organisations[coh81] Each of these algorithms and their host stores are designed to support a particular pattern of use or scale of data. For example, the garbage collector employed in the S algol[mor82] heap storage uses a single list of free storage[mcc60] Since S algol does not create objects at a very high rate the cost of object creation and garbage collection only has a small effect on overall system performance. In contrast, systems supporting first class procedures may make intensive use ....

....erroneous programs modifying capabilities or manufacturing their own. 1. 3 PS algol and the CPOMS The concept of persistence arose from work on integrating programming languages with database systems[atk78] As part of this research, persistence was added to the programming language S algol[mor82], requiring solutions to be found for each of the five problems described above. The resulting programming language, PS algol[atk83c] was developed to test the hypothesis that persistence could be added to a programming language with a minimum of change. That is, as far as possible, the provision ....
....languages that included Pascal, newer programming languages have been developed that use more sophisticated type systems and also reduce the potential for spurious errors. Some examples of these newer programming languages are Ada[ada83] CLU[lis81] Galileo[alb85b] KRC[tur82] ML[mil85] Salgol [mor82], PS algol[psa88] and SASL[tur79] Each of these programming languages provide one or more of the following features: a) abstract data types, b) first class procedure values, c) type inheritance, d) the explicit initialisation of all data before it is used, e) automatic bounds checking on ....
