- building the necessary plumbing to support more functions with decent runtime performance. This is also necessary towards the long-term goal of loadable library modules. - added new RainerScript function "tolower"

/* 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.
