-/* The vmprg object.
- *
- * The program is made up of vmop_t's, one after another. When we support
- * branching (or user-defined functions) at some time, well do this via
- * special branch opcodes. They will then contain the actual memory
- * address of a logical program entry that we shall branch to. Other than
- * that, all execution is serial - that is one opcode is executed after
- * the other. This class implements a logical program store, modelled
- * after real main memory. A linked list of opcodes is used to implement it.
- * In the future, we may use linked lists of array's to enhance performance,
- * but for the time being we have taken the simplistic approach (which also
- * reduces risk of bugs during initial development). The necessary pointers
- * for this are already implemented in vmop. Though this is not the 100%
- * correct place, we have opted this time in favor of performance, which
- * made them go there.
