Who comes from the ZX Spectrum world knows perfectly these commands that are his bread and butter. <\/span>For QL there is not much difference except the lack of border area (thankfully) but the command purpose is only to draw a border, in the output window, having the thickness chosen by the user. <\/span>Therefore the thickness is 0 by default. The syntax is the following:
\n<\/span>BORDER thickness,color<\/em>
\n<\/span>This command draws a colored border in the display area<\/span>. <\/span>Therefore if you want to create a border in another area of the screen, you must use the WINDOW statement which, through the 4 parameters, “draws” a rectangle in the desired area of the screen. <\/span>Hence the useful BORDER command will clearly mark the WINDOW output area on the screen. <\/span>If you want you can create a “multicolored border” by simply making a thick colored border followed by other borders having decreasing thicknesses.
\n<\/span><\/span><\/span>Example:<\/span><\/span><\/span><\/span><\/p>\n


\n<\/span>470 BORDER 7.2
\n<\/span>480 BORDER 6.3
\n<\/span>490 BORDER 5.4
\n<\/span>500 BORDER 4.5
\n<\/span>510 BORDER 3.6<\/span><\/span><\/p>\n


\n<\/span>This will create a border into another thus giving an appearance of depth. <\/span>It must be said that the print commands will end up in the edge area overlapping<\/span><\/span> the rectangle generated by the command. Therefore is recommended to type:
\n<\/span><\/span>AT x, y: PRINT “text”
\n<\/span>Paper works exactly as for the ZX Spectrum although its effect is achieved only after a CLS.
\n<\/span>If the PRINT command follows the PAPER one, as in ZX Spectrum it will color the background of the printed text.
\n<\/span>Finally INK defines the color for text or graphical drawings (on QL it can also be applied to points and lines).
\n<\/span>As regards the color range, the QL is not limited as the ZX because in addition to the classic system colors (depending on if you are using a classic QL or an emulator or an expanded system), the colors will be mixed through the screen system in order to offer more color shades.<\/span><\/span><\/p>\n
