However, the <i id="yiv5919056072yui_3_16_0_1_1453641578501_19857" class="">line space </i>of a text line is fixed in Original Oberon (to 12 pixels). But if one changes the font size of a line to number that is <i id="yiv5919056072yui_3_16_0_1_1453641578501_21432" class="">larger</i> than 12 (for example to 24 pixels using Edit.ChangeFont Times24.Scn.Fnt), then the line with the larger font size will simply overlap the preceding one, and the result will not look particularly nice (of course, the user can always insert an extra line in that case to avoid the overlapping..).</div><div id="yiv5919056072AppleMailSignature" class=""><br clear="none" id="yui_3_16_0_1_1453641578501_26701" class=""></div><div dir="ltr" id="yiv5919056072AppleMailSignature" class="">In Experimental Oberon the <i id="yiv5919056072yui_3_16_0_1_1453641578501_19924" class="">line space </i>itself can have <i id="yiv5919056072yui_3_16_0_1_1453641578501_19749" class="">any</i> value (a line can thus accommodate text of <i id="yui_3_16_0_1_1453641578501_26706" class="">any</i> height, with automatic readjustments of the remaining lines). It was included as it turned out to be fairly easy to make that possible (but of course, it also means that text rendering can no longer be done in a single pass as was the case in Original Oberon; however, there is practically no measurable performance penalty of using two passes instead of one for text rendering, because the text line to be rendered will be read from the file <i id="yui_3_16_0_1_1453641578501_26708" class="">buffer</i> during the second pass and not from the file again).</div><div dir="ltr" id="yiv5919056072AppleMailSignature" class=""><br clear="none" id="yui_3_16_0_1_1453641578501_26711" class=""></div><div dir="ltr" id="yiv5919056072AppleMailSignature" class="">Note that the code in Experimental Oberon mainly serves <i id="yiv5919056072yui_3_16_0_1_1453641578501_21117" class="">experimental</i> purposes, e.g. to find out whether a proposed feature is actually worth the effort or not. Not saying that a particular feature (e.g. variable line spaces) is actually needed in all use cases. One can always find arguments for or against a proposed feature. If all you are doing is coding, then variable line spaces are a dispensable luxury indeed.</div><div id="yiv5919056072AppleMailSignature" class=""><br clear="none"
