it is not so strange when you run this after that:

 Code:
break on

$iRC=SETOPTION('NoVarsInStrings','on')
$iRC=SETOPTION('NoMacrosInStrings','on')

$s = '@'
$d = '@@'

? " asc value single = " asc($s)
? " asc value double = " asc($d)
?
? " chr from asc single = " chr(asc($s))
? " chr from asc double = " chr(asc($d))

get $iRC
