RPL character set

<h2 id="overview">Overview</h2> <p>In 1986,<a class="footnote-ref" id="fnref:5" href="#fn:5"><sup>5</sup></a> the <i>original</i> series of RPL calculators (<a href="/facts/HP-28_series/RgX0wdE3">HP-28 series</a>) as well as the HP 82240A <a href="/facts/Thermal_printer/Lc0I2XGJ">thermal printer</a> used a <a href="/facts/HP_82240A_character_set/txpWXPBw">modified variant</a> of the <a href="/facts/HP_Roman-8/txpWXPBw">HP Roman-8</a> character set, of which characters above 147 could not be displayed on the calculator, only be printed.<a class="footnote-ref" id="fnref:6" href="#fn:6"><sup>6</sup></a><a class="footnote-ref" id="fnref:7" href="#fn:7"><sup>7</sup></a><a class="footnote-ref" id="fnref:8" href="#fn:8"><sup>8</sup></a> </p><p>This changed with the introduction of the HP 82240B printer in 1989<a class="footnote-ref" id="fnref:9" href="#fn:9"><sup>9</sup></a> and the <a href="/facts/HP_48_series/FonQov9J">HP 48 series</a> in 1990, which came with a new character set now based on ECMA 94 / ISO 8859-1 instead of HP Roman-8, but with the control codes in the range 128 to 159 (0x80 to 0x9F) being replaced by additional displayable characters. Compared to ISO 8859-1, code point 127 (0x7F) showed a medium shaded gray box like in the former HP Roman-8 based character set. Code points 131 (0x83) to 142 (0x8E) were also taken over from the former HP Roman-8 based character set. In addition to this, code point 31 (0x1F) was used for ellipsis (<a href="/facts/%25E2%2580%25A6/JgLA051B">…</a>)<a class="footnote-ref" id="fnref:10" href="#fn:10"><sup>10</sup></a><a class="footnote-ref" id="fnref:11" href="#fn:11"><sup>11</sup></a> and code points 169 (0xA9) and 174 (0xAE) showed ambiguous glyphs which could be viewed as inverse circled number <a href="/facts/%25E2%259D%25B8/6QzW9RkE">❸</a> or <a href="/facts/Copyright_symbol/vKDWhSGv">copyright symbol</a> (<a href="/facts/%25C2%25A9/vKDWhSGv">©</a>) and as <a href="/facts/%25E2%259D%25B7/u5WC44t9">❷</a> or <a href="/facts/Registered_trademark/lLGeMyUG">registered trademark</a> symbol (<a href="/facts/%25C2%25AE/lLGeMyUG">®</a>), respectively.<a class="footnote-ref" id="fnref:12" href="#fn:12"><sup>12</sup></a><a class="footnote-ref" id="fnref:13" href="#fn:13"><sup>13</sup></a> This <i>first version</i> of the character set also had a <a href="/facts/Non-breaking_space/lBPo5IS6">non-breaking space</a> at position 160 (0xA0).<a class="footnote-ref" id="fnref:14" href="#fn:14"><sup>14</sup></a><a class="footnote-ref" id="fnref:15" href="#fn:15"><sup>15</sup></a><a class="footnote-ref" id="fnref:16" href="#fn:16"><sup>16</sup></a> </p><p>Translation from HP-48 to HP-28 character set:<a class="footnote-ref" id="fnref:17" href="#fn:17"><sup>17</sup></a> </p> HP translation vector<table><tbody><tr><td></td><td>0</td><td>1</td><td>2</td><td>3</td><td>4</td><td>5</td><td>6</td><td>7</td><td>8</td><td>9</td><td>A</td><td>B</td><td>C</td><td>D</td><td>E</td><td>F</td></tr><tr><td>8x</td><td>0xA0</td><td>0x7F</td><td>0x7F</td><td>0x83</td><td>0x84</td><td>0x85</td><td>0x86</td><td>0x87</td><td>0x88</td><td>0x89</td><td>0x8A</td><td>0x8B</td><td>0x8C</td><td>0x8D</td><td>0x8E</td><td>0x76</td></tr><tr><td>9x</td><td>0x5E</td><td>0x7F</td><td>0x7F</td><td>0x7F</td><td>0x7F</td><td>0x7F</td><td>0x7F</td><td>0x7F</td><td>0x7F</td><td>0x7F</td><td>0x7F</td><td>0x7F</td><td>0x7F</td><td>0x7F</td><td>0xFC</td><td>0x7F</td></tr><tr><td>Ax</td><td>0x20</td><td>0xB8</td><td>0xBF</td><td>0xAF</td><td>0xBA</td><td>0xBC</td><td>0x7C</td><td>0xBD</td><td>0xAB</td><td>0x63</td><td>0xF9</td><td>0x92</td><td>0x7E</td><td>0x2D</td><td>0x52</td><td>0xB0</td></tr><tr><td>Bx</td><td>0xB3</td><td>0xFE</td><td>0x97</td><td>0x98</td><td>0xA8</td><td>0x8F</td><td>0xF4</td><td>0xF2</td><td>0x2C</td><td>0x31</td><td>0xFA</td><td>0x93</td><td>0xF7</td><td>0xF8</td><td>0xF5</td><td>0xB9</td></tr><tr><td>Cx</td><td>0xA1</td><td>0xE0</td><td>0xA2</td><td>0xE1</td><td>0xD8</td><td>0xD0</td><td>0xD3</td><td>0xB4</td><td>0xA3</td><td>0xDC</td><td>0xA4</td><td>0xA5</td><td>0xE6</td><td>0xE5</td><td>0xA6</td><td>0xA7</td></tr><tr><td>Dx</td><td>0xE3</td><td>0xB6</td><td>0xE8</td><td>0xE7</td><td>0xDF</td><td>0xE9</td><td>0xDA</td><td>0x82</td><td>0xD2</td><td>0xAD</td><td>0xED</td><td>0xAE</td><td>0xDB</td><td>0xB1</td><td>0xF0</td><td>0xDE</td></tr><tr><td>Ex</td><td>0xC8</td><td>0xC4</td><td>0xC0</td><td>0xE2</td><td>0xCC</td><td>0xD4</td><td>0xD7</td><td>0xB5</td><td>0xC9</td><td>0xC5</td><td>0xC1</td><td>0xCD</td><td>0xD9</td><td>0xD5</td><td>0xD1</td><td>0xDD</td></tr><tr><td>Fx</td><td>0xE4</td><td>0xB7</td><td>0xCA</td><td>0xC6</td><td>0xC2</td><td>0xEA</td><td>0xCE</td><td>0x81</td><td>0xD6</td><td>0xCB</td><td>0xC7</td><td>0xC3</td><td>0xCF</td><td>0xB2</td><td>0xF1</td><td>0xEF</td></tr></tbody></table> <p>In a <i>revision</i> of this character set in 1999, code point 160 (0xA0) was redefined to hold the <a href="/facts/Euro_sign/boK32Hs4">euro sign</a> (€) in the <a href="/facts/HP_49%2f50_series/CHJ2toxY">HP 49/50 series</a> (including the <a href="/facts/HP_48gII/CHJ2toxY">HP 48gII</a>),<a class="footnote-ref" id="fnref:18" href="#fn:18"><sup>18</sup></a><a class="footnote-ref" id="fnref:19" href="#fn:19"><sup>19</sup></a><a class="footnote-ref" id="fnref:20" href="#fn:20"><sup>20</sup></a><a class="footnote-ref" id="fnref:21" href="#fn:21"><sup>21</sup></a> now deviating from ISO 8859-1.

HP part number F2224-90010. Archived (PDF) from the original on 2016-03-03. Retrieved 2016-08-06. The original hp 38g only had the function INVERSE(...) and the -1 operator was added for convenience sake in the hp 39g, released in 2000. To do this the creators had to borrow one of the existing unused characters, the 3 character, and convert it into the -1 operator. However, they forgot to change it in the CHARS view and this error has never been fixed in any of the successive models! <a href="http://www.hp.com/ctg/Manual/c00829737.pdf" target="_blank">http://www.hp.com/ctg/Manual/c00829737.pdf</a> <a href="#fnref:24" class="footnote-back-ref">↩</a></p></li> <li id="fn:25"><p>Lehmann, Alexander (2000-08-16).
