But that makes no sense, it is whitespace, and it has semantic significance (hence being significant). Whitespace was not significant in older versions of Fortran, and that allowed you to write DO30I=10,100
which was interpreted as DO 30 I = 10, 100
An amusing bug I saw in Expert C Programming mentioned how somebody once typed e dot instead of a comma, and DO 30 I = 10. 100
ended up interpreted as a simple real assignment: DO30I = 10.1
