Value Name Parameter Meaning &14 20* DC4 Clear from, and including, the current character position to the end of window. Fills affected cells with the current Paper Ink. &15 21 NAK Turn off text screen. The screen will not react to anything sent to it until after an ACK (&06 6) is sent. &16 22 SYN Oto 1 Parameter MOD 2. Transparent option. 0 disables, 1 enables. &17 23 ETB Oto3 Parameter MOD 4 o sets normal graphics ink mode 1 sets XOR graphics ink mode 2 sets AND graphics ink mode 3 sets OR graphics ink mode &18 24 CAN Exchange Pen and Paper Inks. &19 25 EM Oto255 Set matrix for user definable Oto255 character. Equivalent to a Oto255 S Y M B 0 L command. Takes nine Oto255 parameters. The first parameter Oto255 specifies which character's Oto255 matrix to set. The next eight Oto255 specify the matrix. The most Oto255 significant bit of the first Oto255 byte corresponds to the top left hand pixel of the character cell, the least significant bit of the last byte corresponds to the bottom right hand pixel ofthe character cell. &1A 26 SUB 1 to80 Set Window. Equivalent to a 1 to80 WIN DO W command. The first two 1 to25 parameters specify the left and 1 to25 right hand edges of the window - the smaller value is taken as the left edge, the larger the right. The second two parameters specify the top and bottom edges of the window -the smaller value is taken as the top edge, the larger the bottom edge. For your reference .... Chapter 7 Page 5
Value Name Parameter Meaning &1B 27 ESC No effect. Ignored. &1C 28 FS Oto 15 Set Ink to a pair of colours. Oto31 Equivalent to an INK command. Oto31 The first parameter (MOD 16) specifies the Ink, the next two (MOD 32) the required colours. (Parameter values 27 to 31 are un-defined colours.) &1D 29 GS Oto31 Set Border to a pair of colours. Oto31 Equivalent to aB 0 R D E R command. The two parameters (MOD 32) specify the two colours. (Parameter values 27 to 31 are un-defined colours.) &1E 30 RS Move cursor to top left hand corner of window. &1F 31 US 1 to80 Move cursor to the given 1 to25 position in the current window. Equivalent to a LO CAT E command. The first parameter gives the column to move to, the second gives the line. The housekeeping of the 6128 is provided by a sophisticated real time operating system. The operating system 'directs the traffic' through the computer from the input to the output. It primarily interfaces between the hardware and the BASIC interpreter - for example the ink flashing function, where BASIC passes the parameters - and the operating system gets on with the task, with one part determining what is required - and the other part determining the timing of these events. The machine operating system is generally referred to as the 'firmware', and comprises the machine code routines that are called by the high level commands in BASIC.
