It's a poor feature. A string starting with " followed by a digit
starts an octal input, not necessarily a number. Thus your input

make file a variable of type Int and a value of octal 040301, decimal
16577.

If you enter file="0403010932 then the variable type is long and the
value in decimal is 543213431.

The underline character is not a valid octal digit, hence "Syntax error".
