INT 03 - Columbia PCs (desktop,VP portables) - ROM(Read-Only Memory) A memory for program storage which may not be changed by the program as it runs. DEBUGGER
Desc:	invokes the ROM(Read-Only Memory) A memory for program storage which may not be changed by the program as it runs. Debugger if INT 03 has not been revectored; equivalent
	  to pressing Esc on booting.

INT 03 - Realia COBOL - DEBUGGER SUPPORT                                        
Note:	Realia COBOL checks for a signature eight bytes prior to the interrupt
	  handler when it starts up
BUG:	if the offset of the INT 03 vector is less than 8, the compiler and
	  all executables generated by it will crash the system

Notes:	the INT 03h instruction which invokes the debugger must be followed by
	  a JMP SHORT and the signature string "WVIDEO"
	to check whether this interface is available, define a public byte
