$loc = index($rec, $HexValue); OR @sub_field1 = split(/$HexValue/, $rec);
Where the $HexValue is either a variable that contains my hex'01' or the absolute value itself.
The chr function returns the character with a given ASCII (or Unicode) value and you can use \x01 inside of double-quoted strings, so e.g. to have a space, you could write:
$char = chr 32; # decimal
$char = chr 0x20; # hexadecimal
$char = "\x20"; # hexadecimal
$char = "\040"; # octal
$HexValue = v32; # decimal
or
$string = "abc\x{20}def 123\x{20}456";
etc.Is that what you need?
