153. View extended highlights ~~~~~~~~~~~~~~~~~~~~~~~~ Within VIEW there are two commands known as Highlight-1 and Highlight-2, which are used to mark parts of the text to be printed in a special way. The printer is controlled by a printer driver routine within View, which interprets the Highlight commands and converts them into codes which the particular type of printer in use can understand. Normally, Highlight-1 inserts an underline "_" character into the screen text and sends a code 128 to the printer driver, which in turn produces underlined text on the printer. Similarly, Highlight-2 inserts an asterisk, sends code 129 and produces bold printed text. To improve on this limited situation, use can be made of what Acorn call Extended Highlights. By resetting Highlight-2 to produce code 130, and loading one of the Acorn Printer Driver routines from disc, (costs about #10-00), various printer effects can be called upon by using combinations of Highlights 1 and 2. For example, italics can be created using Highlights 2+1+2, which would appear as "*_*" on the screen. The Acorn Printer Driver disc contains routines for most common printers, and a program is available to create your own if you wish. Highlight 2 is reset by entering as the first line on the edit screen:- HT 2 130 . The function keys, in conjunction with and , can be used to provide the appropriate codes, which can be installed using a !BOOT setup; *FX228,1 enables the facility. For further explanation of the facilities, refer to the Printer Driver User Guide and your Printer User Guide. Remember to include all the spaces when typing in, as they are vital, and don't confuse "!" with "|". For clarity, spaces are shown as a "-", and note that some definitions have a space at the END, not just in the middle. *WORD *FX228,1 *KEY0|!|- *KEY1|!!|!!|!! *KEY2|!! *KEY3|!!|!|- *KEY4|!!|!! *KEY5|!!|!!|!|- *KEY6|!!|!|-|!|- *KEY7|!!|!|-|!! *KEY8|!!|!|-|!|-|!|- The facilities created using + Function keys are:- f0 f1 f2 f3 f4 f5 Under- Bold Next character Begin Begin Cancel Sub line On/Off to extension Subscript Superscript or Super- set script f6 f7 f8 Alternative Italics Reset Font on/off on/off
