//
// WDEB386 Dot commands
//
// This file and the file dbgdota.asm implement the .W dot commands on
// behalf of wdeb386. W32ParseDotCommand is called to parse and execute
// the dot commands.
//
// *All* memory that is accessed while processing a dot command *must*
// be present. If it is not, a page fault will occur which can, and
// likely will, result in a very large amount of system code being
// executed. This will change the state of the system as it is being
// debugged, and can lead to unexpected, incorrect or fatal behaviour.
//
// The convention used by the .W commands to handle dumping structures
// that reside in not-present memory is to display the not-present
// address in brackets ("[]"). The user may then use the '.MM' command
// to force the memory present if desired (note that this action has
// all of the pitfalls described above), and then reissue the .W command.
//
// All code and data directly associated with the .W commands reside in
// the LOCKCODE and LOCKDATA segments. The InitDotCommand function
// (dbgdota.asm) locks these segments in memory.
