DO Loops HP FORTRAN 77/V does not allow jumping into the middle of a DO loop. DO loops with this feature in FORTRAN 66/V require a logic change in HP FORTRAN 77/V. The migration aid automatically inserts the CONTROL ONETRIP compiler directive in converted programs. However, new programs must specify this directive if they require all loops to be executed at least once.
