+// z/OS ptrace implementation notes:
+//
+// This file provides ptrace wrappers for z/OS that match the Linux API as closely
+// as possible. However, there are fundamental differences in how z/OS implements
+// process tracing compared to Linux:
+//
+// 1. SYSTEM CALL INTERFACE:
+//    - z/OS uses BPX4PTR (5 parameters) vs Linux ptrace syscall (4 parameters)
+//    - The 5th parameter (buffer) is used for block operations
+//
+// 2. MEMORY OPERATIONS:
+//    - z/OS: PT_READ_BLOCK/PT_WRITE_BLOCK for efficient block transfers
+//    - Linux: PTRACE_PEEKTEXT/POKETEXT for word-by-word access
+//
+// 3. REGISTER OPERATIONS:
+//    - z/OS: PT_READ_GPR/PT_WRITE_GPR with register number for 64-bit values
+//    - Linux: PTRACE_GETREGSET/SETREGSET with iovec structure
+//
+// 4. SINGLE-STEPPING:
+//    - z/OS: No native single-step; requires temporary breakpoints or PER
+//    - Linux: PTRACE_SINGLESTEP natively supported
+//      a) Read instruction at current PSW
+//      b) Calculate next instruction address (handle branches)
+//      c) Set temporary breakpoint (SVC 144 = 0x0A90) at next address
+//      d) Continue execution until breakpoint hit
+//      e) Restore original instruction and adjust PSW
+//
+// 5. SYSCALL TRACING:
+//    - z/OS: No PTRACE_SYSCALL equivalent; requires breakpoint-based approach
+//    - Linux: PTRACE_SYSCALL stops at syscall entry/exit
+//      a) Identify BPX syscall vector location
+//      b) Set breakpoints at syscall entry points
+//      c) Detect BASR instructions calling into syscall vector
+//      d) Parse arguments from registers before/after syscall
+//
+// 6. LIMITATIONS:
+//    - PtraceSetOptions: No equivalent (returns ENOSYS)
+//    - PtraceGetEventMsg: No equivalent (returns ENOSYS)
+//    - PtraceSingleStep: Requires complex implementation (returns ENOSYS)
+//    - PtraceInterrupt: No equivalent (returns ENOSYS)
+//    - PtracePokeUser: No PT_WRITE_U (returns ENOSYS)
+//
+// For reference implementations of single-stepping and syscall tracing on z/OS,
+
+// ptrace is the basic wrapper for BPX4PTR on z/OS.
+// Note: z/OS ptrace (BPX4PTR) takes 5 parameters vs 4 on Linux/Darwin.
+// The 5th parameter (buffer) is used for operations like PT_READ_BLOCK/PT_WRITE_BLOCK.
+//
+// data is an integer-valued argument (signal number, register index, byte count,
+// or a target-process address). It is not a Go-managed pointer. We must not pass
+// it to Bpx4ptr as unsafe.Pointer(data) because the garbage collector would treat
+// that integer as a pointer and may crash trying to follow it.
+//
+// Instead we inline the parms array that Bpx4ptr would construct, placing &data
+// at parms[3]. BPX4PTR dereferences parms[3] to obtain the data value, so it
+// receives data unchanged while the GC only ever sees a valid stack pointer.
