; Simple example machine language program to read and print a line

START a10   ; start address of the program, initialise PC to this

AT a0
0000 0000 0000 0000     ; a0: memory cell where the character will be stored

AT a10                  ; store the following data items (instructions) into
                        ; memory from a10 onwards
110101  0000 0000 10    ; a10: trap 2 (Get), read character
001 010 0000 0000 00    ; a11: store a0, store the character
000 111 0000 0010 10    ; a12: compare EOL (End-Of-Line character)

110101  0000 0000 11    ; a14: trap 3 (Put), print character
101000  0000 0010 00    ; a15: jump to a10, jump to start of loop
110101  0000 0000 11    ; a16: trap 3 (Put), print EOL character
110101  0000 0000 01    ; a17: trap 1 (Halt), stop the program
