Fix basic output target to keep lines below 249 characters The line length limiter in the basic output was not properly moving to the next before 249 characters, which is the limit Color Basic can read in an ASCII basic program. Changed the line limiter to 240 from 247 to account for a possible 5 digit number plus a comma and just a bit of extra breathing space.
