+     * to be executed.</p>

+     * <p>The parameters provided allow the command to manipulate the operand stack, modify the local variables, and control the flow

+     *
+     * <p>The exact behavior of this method will depend on the specific instruction being executed (e.g., arithmetic, branching,
+     * function calls, etc.). For example, a `CALL` instruction will modify the call stack by pushing a new frame,
+     * while a `POP` instruction will remove an item from the operand stack.</p>

+     * @param parts              The array of instruction parameters, which usually includes the operator and related arguments
+     *                           (such as target addresses, values, or function names). These parameters may vary based on
+     *                           the instruction being executed.
+     * @param currentPC          The current program counter-value, indicating the address of the instruction being executed.
+     *                           This value is typically incremented after the execution of each instruction to point to the next one.
+     * @param operandStack       The virtual machine's operand stack manager, responsible for performing operations on the operand stack,
+     *                           such as pushing, popping, and peeking values.
+     * @param localVariableStore The local variable store, typically used to manage method-local variables during instruction execution.
+     *                           The store may not be used in every command but can be leveraged by instructions that require access
+     *                           to local variables.
+     * @param callStack          The virtual machine's call stack, which keeps track of the method invocation hierarchy. It is used by
+     *                           instructions that involve method calls or returns (such as `CALL` and `RETURN` instructions).
+     * @return The updated program counter-value, typically the current program counter-value incremented by 1, unless the
+     * instruction modifies control flow (such as a `JUMP` or `CALL`), in which case it may return a new address
+     * corresponding to the target of the jump or the subroutine to call.
