Teletext displayed alpha-numeric character set (modes 7 and 135)

Codes in the range 0 to 31 are control codes which correspond to the VDU codes

described in Appendix 7.

Codes in the range 128 to 159 are the Teletext control codes which affect

subsequent characters on the same line (see page C61). The characters shown

in the table below are those displayed under the effect of an alpha-numeric

control code.

Each code produces a unique character. Thus VDU 78 or PRINT CHR$(78)

would display an N since column 70, row 8 shows an N.
