When evaluating expressions, strings are automatically coerced to integers where the expression implies an integer is required and a string is supplied.e.g. a1 .set 0x123 fred .set a1 + "0xBC00" ; automatic coercion of string to integer .dw fred ; is equivalent to .dw 0xBD23 ---------------------- Both operands of the == comparison operator are required to be of the same type (either both strings or both integer). The right hand operand is automatically coerced to be of the same type as the left operand if it is different. 2 == 1 left and right hand operands are integers so perform integer EQUALS comparison which yields 0 "2" == 1 left hand operand is string and right hand operand is integer so coerce right hand operand to string and perform string EQUALS comparison which yields 0 "2" == "1" left and right hand operands are strings so perform string EQUALS comparison which yields 0 2 == "1" left hand operand is integer and right hand operand is string so coerce right hand operand to integer and perform integer EQUALS comparison which yields 0BEWARE:Coercion from string to integer requires that a vaild number is present at the start of the string that is to be coerced. If the string does not hold a valid number then a zero is returned. A string that contains a partly valid number at its start will have all the digits upto the first invalid digit converted to an integer.See thee.g. "0109" The leading 0 character indicates that the remainder of the number is in octal (base 8), so the number is interpreted as as the valid octal number 010 (which is 8 in decimal) followed by the invalid octal character 9. This may lead to some confussion initially since the returned number when printed normally will show up as 8 which does not appear anywhere in the original "0109" string.description of numbersfor further information on valid string to integer coercion
