ASPL Basic Set Operations
Aside of the set operators that perform group operations on set variables (and are termed setadic operators), ASPL has several basic operators that are are built within the software. The basic operators perform essential operations on set variables such as: #, density, push, pop, copy, split, common, purge, copy, merge, lmerge, gmerge, equal, subset , disjoint , superset, similarity.The operator = is the assignment operator and is a binary operator: always preceded by a symbol representing a named set variable, and can be followed by either a set variable, or by an expression (a setadic operator and its arguments).
The following operators *= *=* .=* are "assignment transform operators" and are always preceded by a symbol representing a named set variable, and followed by one or more set variables.
The following chapter consists of pages describing ASPL Basic Operators.
