|
|
<a name="l3"></a>A </span><span class=cF2>Char</span><span class=cF0>acter is a single byte holding an ASCII code for a letter, num or sym.
|
|
<a name="l4"></a>The </span><span class=cF2>TempleOS</span><span class=cF0> term is a </span><span class=cF2>U8</span><span class=cF0>.
|
|
<a name="l5"></a>
|
|
<a name="l6"></a>Standard ASCII values range from 0 to 127. Values below 32 are ctrl key's. So,
|
|
<a name="l7"></a>an ASCII #3 is a </span><span class=cF2><CTRL-c></span><span class=cF0>. TempleOS uses a few nonstandard values below 32.
|
|
<a name="l8"></a>See </span><a href="/Wb/Kernel/KernelA.HH.HTML#l3456"><span class=cF4>Char Definitions</span></a><span class=cF0>.

<a name="l9"></a>
|
|
<a name="l10"></a>ASCII #5 is the cursor location in a saved file.
|
|
<a name="l11"></a>ASCII #28 is </span><span class=cF2><SHIFT-ESC></span><span class=cF0>.
|
|
<a name="l12"></a>ASCII #31 is a </span><span class=cF2><SHIFT-SPACE></span><span class=cF0>.
|
|
<a name="l13"></a>
|
|
<a name="l14"></a>TempleOS ASCII is 8-bit instead of 7-bit, so it also uses the range from
|
|
<a name="l15"></a>128-255. Press </span><span class=cF2><CTRL-ALT-a></span><span class=cF0> to see shapes for 128-255. Technically, </span><span class=cF2><CTRL-ALT-

<a name="l17"></a>
|
|
<a name="l18"></a>A </span><span class=cF2>Key</span><span class=cF0> is typically specified with a scan code. TempleOS scan codes contain the

<a name="l21"></a>

<a name="l22"></a>TempleOS stores scan codes in 8 bytes.

<a name="l23"></a> </span><span class=cF2>Byte 0</span><span class=cF0> is the code. NumPad keys, SHIFT, ALT, CTRL and GUI keys combined.

<a name="l26"></a>The upper 4-bytes are copied from lower 4-bytes.
|
|
<a name="l27"></a> </span><span class=cF2>Byte 4</span><span class=cF0> is the code. Left, Right and NumPad keys distinct.
