Package svm

package svm

The S-Port Simula Virtual Machine.

The Simula Virtual Machine consists of:

  • a set of Data Segments of Values

  • a set of Program Segments of SVM-Instructions.

    All SVM_Instruction have an 'execute' method which will carry out its task and finally update the PSC.

  • a Runtime Stack of values

  • a Program Sequence Control (PSC) pointer.

A SVM-Program is executed by a control loop like:

try {
	PSC = mainEntry;
	while(true) PSC.execute();
} catch(EndProgram eprog) { return; }
