set128Controls()

Calls to set128Controls() allow the user to define a character to be used to represent a 128 control code in data.

set128Controls(int I, int J)

where I is the index in the control code table (below) and j is the ASCII value of the character that will be used in data to represent that control code. If I is less than zero then the value of J is ignored and the default control code characters are assumed.

The current ASCII value used to represent a control code may be obtained using

J=get128Control(I).

Where the return value is the ASCII value of the control code.

If I is less than 0 in the get128Control() call then the call returns 0 if the default values for control codes are in use, or -1 if programmed values are in use.

The control codes, their index values and default character representation are shown in the table below. The Key value is the sequence that may be typed on the numeric keypad (WHILE HOLDING DOWN THE <Alt> key) to generate the default character.
