HEX to ASCII converter

[SUF6NEWBIE]

Well..when there is a need - 'make it happen 'Capin'

this stuff wil convert a HEX string to ASCII standard character output.
There is know doubt some pure LUA code for this, I could not find any..

-- Functions to convert Hex data(string) to ASCII


-- read the 'ASCII.TXT' to a table - at say 'on startup' actions

G_HX_CONV_T = TextFile.ReadToTable(_SourceFolder.."\\AutoPlay\\Docs\\ASCII.TXT");


--SOHEXGET
function HEXGET()

MainWork_str = "";
		
		--strHex = "whatever"; --eg: returned string from say a 'target registry read'
			--good example is reading the Os 'dos devices' hex strings
			--HKLM\SYSTEM\MountedDevices\ --read the values to a table and cycle through						
		
		--restructure returned Hex string for correct ASCII converion		
		strHex = String.Replace(strHex, " ", ",", false); --replace all " " with ","
		strHex = String.Replace(strHex, "00,", "", false); --now remove all "00,"
		strHex = String.Replace(strHex, ",", "", false); --now remove all ","
		hxlength = String.ToNumber(String.Length(strHex));		
		hxmidstr = String.Mid(strHex, 1, 2);
							
		while (hxlength > 0) do
		HEXASCII(); -- call the ASCII converter	
		--reset for next hex find		
		hxmidstr = String.Mid(strHex, 1, 2);
		hxlength = String.ToNumber(String.Length(strHex)); --for loop
			if (hxlength == 0) then
			strASCII = MainWork_str; -- the final converted string
			Dialog.Message("Hex-ASCII: Debug Info only", strASCII); 			
			break; --all done
			end											
		end --while	
		
end
--EOHEXGET

--SOHexcovert
function HEXASCII()


	for valindex, valline in G_HX_CONV_T do
		--reset vars
		Decval = nil;
		ascichar = nil;
		hxvalname = nil;
		hxvalname = String.Find(valline, hxmidstr.."=", 1, true);
		if (hxvalname == 1) then
		hxvalpos = String.Find(valline, "=", 1, false);
		Decval = String.TrimRight(String.Mid(valline, hxvalpos +1, -1), nil);
		ascichar = String.Char(Decval);			
		MainWork_str = String.Concat(MainWork_str, ascichar);	
		strHex = String.Mid(strHex, 3, -1); --remove converted from string for next
		break;
		end				
	end--loop

end
--EOHexcovert

download the file below I constructed (contains Hex-Dec - first 127 chars)
and include in your 'source folder'.

Is someone has something else - could ya offer it up--thanks

There is a function in LUA string.format where you can use a %x or %X option to convert to hex and -c to convert to the char value.
