インテル® Fortran コンパイラー 19.0 デベロッパー・ガイドおよびリファレンス
Some language features, considered redundant in older versions of the Fortran Standard, are identified as obsolescent in the current Fortran Standard.
Intel® Fortran flags these features if you specify compiler option stand.
Other methods are suggested to achieve the functionality of the following obsolescent features:
ENTRY statement
To replace this functionality, it is recommended that you use multiple module procedures that can access shared data in the module.
Alternate returns (labels in an argument list)
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 use a CASE construct to test the value and perform operations.
Arithmetic IF
To replace this functionality, it is recommended that you use an IF statement or construct.
Assumed-length character functions
To replace this functionality, it is recommended that you use one of the following:
An automatic character-length function, where the length of the function result is declared in a specification expression
A subroutine whose arguments correspond to the function result and the function arguments
Dummy arguments of a function can still have assumed character length; this feature is not obsolescent.
CHARACTER*(*) form of CHARACTER declaration
To replace this functionality, it is recommended that you use the Fortran 90 forms of specifying a length selector in CHARACTER declarations (see Declaration Statements for Character Types).
Computed GO TO statement
To replace this functionality, it is recommended that you use a CASE construct.
DATA statements among executable statements
This functionality has been included since FORTRAN 66, but is considered to be a potential source of errors.
Fixed source form
Newer methods of entering data have made this source form obsolescent and error-prone.
The recommended method for coding is to use free source form.
Shared DO termination and termination on a statement other than END DO or CONTINUE
To replace this functionality, it is recommended that you use an END DO statement or a CONTINUE statement.
Statement functions
To replace this functionality, it is recommended that you use an internal function.
