--- Code: ---function charToIdx( %char )
{
if ( strLen( %char ) != 1 )
{
return -1;
}

%count = 16;
%hex = “0123456789ABCDEF“;

for ( %y = 0 ; %y < %count ; %y++ )
{
if ( strStr( %char, collapseEscape( “\\x“ @ getSubStr( %hex, %x, 1 ) @ getSubStr( %hex, %y, 1 ) ) ) == 0 )

return %x + %y;
}
}
}

return -1;
}

function idxToChar( %idx )
{
if ( !strLen( %idx ) || %idx < 0 || %idx > 254 )
{
return ““;
}

%count = 16;
%hex = “0123456789ABCDEF“;

for ( %x = 0 ; %x < %count ; %x++ )

return ““;
}

Sorry for the lack of proper identation, I coded this on a tiny phone keyboard.

charToIdx( char ) => ASCII index of char (0-254).
idxToChar( idx ) => Character representation of the ASCII index.

Ipquarx:
so if you type in 255 it should return the display value of \xFF?

Kalphiter:
And?

What the hell is your question?

If it's a syntax error, it's most likely those quotes that are “ and not "

Brian Smithers:
Your a dolt kalphiter. It says in the title it's a Coding Resource.

Kalphiter:
Either way, all the “ in there will be a problem.

It's in the wrong board, so I didn't think it would've been a resource.
