Here is some sample hex input:

	D00 DA0 DF1 341 DE0 DE1 DE2 3FF 9E7 57B 27F D71 979 597 59B 348
	AEE 9E4 894 D41 972 222 D21 972 120 D20 110 120 215 612 D20 611
	D10 712 D20 1E0 308 4EF DE0 4E0 DE0 160 263 A56 D51 32C A4E D41
	150 253 348 4E0 B5E A6E D60 F3B 3FF 9E4 D41 140 D41 343 9EA E48
	3FF 9E4 D41 347 9ED EE7 D41 000 AAA

(The full assembly program that generated it is given at the end of this file.)

This is what it gives on my sim231 simulator on the shell machine:

	Decimal output written: 0

	Decimal output written: 0

	Hexadecimal output written: 003

	Decimal output written: 65

	Hexadecimal output written: 041

	ASCII output written: A

	Hexadecimal output written: FFF

	Hexadecimal output written: 0A0

	Hexadecimal output written: FF2

	Decimal output written: 0

	Decimal output written: 5

	Decimal output written: 10

	Decimal output written: -5

	Decimal output written: 0

	Decimal output written: 1

	Hexadecimal output written: 341

	Hexadecimal output written: D51

	Decimal output written: 3

	Hexadecimal output written: 000
