TP uses a $ to signify hexadecimal, so you're string should be '$1E'

So to get your string into an integer, just use something like this:

val( '$'+string, num, code);

Re:Convert String to Hex

Hi,
how can I convert a String like this:
'1E'
Into an Integer?

VAL does not work, cause it dosen't recognize the letters as numbers...

Thanks

I am not sure with newer versions, but old TP could convert
the hex number with a preceding '$', like
Val('$'+Num,I,C);

If not, look for "RadixVal" or "ValRadix" (Sorry, I forgot
the name) in the math chapter of the TP-links:

That's not quite so:

var x : word;
k : integer;
begin
Val('$1E', x, k);
writeln (x);
end.

Re:Convert String to Hex

if you put a dollar-sign "$" in front of the string
val will recognize the string as integer
