Fortran 90 did not delete any of the features in FORTRAN 77, but some FORTRAN 77 features were identified as obsolescent.
Intel® Fortran flags these features if you specify compiler option stand.
Other methods are suggested to achieve the functionality of the following obsolescent features:
To replace this functionality, it is recommended that you use an integer variable to return a value to the calling program, and let the calling program test the value and perform operations, using a computed GO TO statement or CASE construct.
To replace this functionality, it is recommended that you use an IF statement or construct.
These statements are usually used to simulate internal procedures, which can now be coded directly.
To replace this functionality, it is recommended that you use character expressions to define format specifications.
To replace this functionality, it is recommended that you branch to the statement following the END IF statement (see IF Construct).
To replace this functionality, it is recommended that you use the character constant edit descriptor (see Character Constant Editing).
To replace this functionality, it is recommended that you use a READ statement that awaits input data.
To replace this functionality, it is recommended that you use integer DO variables and expressions (see DO Constructs).
To replace this functionality, it is recommended that you use an END DO statement (see Forms for DO Constructs) or a CONTINUE statement.
