INT EC - IBMInternational Busiuness MachinesInternational Busiuness Machines) A hardware, software and other service technology company founded in 1911. ROM(Read-Only Memory) A memory for program storage which may not be changed by the program as it runs. BASIC(Beginner's All-purpose Symbolic Instruction Code) A programming language originally designed as a means of teaching FORTRAN.  There are many variations of BASIC with differing capabilities; the majority are interpreted but compiled BASIC is becoming more popular.	All genuine IBMInternational Busiuness Machines personal computers (including the latest PS/2IBM PS/2, any model models) come equipped with a cassette-based BASIC interpreter in ROM. - used while in interpreter

INT EC - Exact - RUNTIME INTERFACE MULTIPLEXOR                                  
	AX = function number (0000h to 0140h)
	STACK:	DWORDDoubleword; four bytes.	 Commonly used to hold a 32-bit segment:offset or selector:offset address. address to return to
		any arguments required by function
Return: STACK:	return address popped, but otherwise unchanged
Desc:	this is the interface from applications to the runtime system by Exact
	  Automatisering B.V. of the Netherlands.  By using this interrupt,
	  it can provide DLL-style capabilities under MS-DOS.
Note:	the interrupt handler removes the return address and flags placed on
	  the stack by the INT EC, then jumps to the appropriate function
