/**
|
|
* @file print.c
|
|
* @brief Implements the OP_PRINT opcode for printing values in the VM.
|
|
*
|
|
* This file handles the OP_PRINT instruction, which prints the top value on the stack
|
|
* to the output buffer. The value is popped from the stack.
|
|
*
|
|
* Behavior:
|
|
* - Pops the value from the stack.
|
|
* - Prints the value to the output buffer.
|
|
*
|
|
* Example:
|
|
* // Bytecode: OP_PRINT
|
|
* // Stack before: [42]
|
|
* // Stack after: []
|
