Hexadecimal editor or PATCH for OpenVMS?

» close window

The Question is:

Is there a hex editor available for OpenVMS?

The Answer is :

  The OpenVMS Debugger can be used as a patching tool (hexadecimal or
  instruction-level), in conjunction with some basic I/O routines that
  are available via the OpenVMS Freeware -- specifically, the ZAP tool
  in the RMS_TOOLS area.
  You can use ZAP to read a block (bucket) of data by VBN (specify X for
  hexadecimal), dump into the debugger with R2 pointing to the buffer,
  EXAMINE/INST or otherwise examine or alter the contents of the buffer,
  GO to get out of the debugger and back into ZAP, then W to write the
  updated data.
