<div dir="auto">Personally, I always hated the awkward <i>Microsoftean</i> way to LOCATE things to PRINT. Two statements? Why?<br><br></div>
<div dir="auto">Instead, always loved the british <i>Sinclairean</i> way, which uses:<br><br></div>
<div dir="auto"><b>PRINT AT <line>, <column></b><br><br></div>
<div dir="auto">Simple, elegant, shorter, it has it all... and even looks more VT100 oriented, where you put coordinate/color/etc. codes right before the payload. Same way to handle attributes (color, etc):<br><br></div>
<div dir="auto"><b>PRINT AT 3, 10; INK 7; PAPER 0; FLASH 1; INVERSE 0; BRIGHT 1; OVER 0;"Hello world."</b><br></div>
<div dir="auto"> <br></div>
<div dir="auto">Could go on with replacing the also Microsoftean LEFT$, RIGHT$ and MID$ abominations with the simpler and more readable Sinclairean syntax<br><br></div>
<div dir="auto"><b>VAR$(<startIndex> TO <endIndex>)</b><br><br></div>
<div dir="auto"> but enough nostalgia trip...<br><br></div>
