![SUBROUTINE]( "SUBROUTINE")
本文介绍了程序内SUBROUTINE声明的无法分类的声明的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
所以我在Fortran 90编写了一个基本的Vigenere Cypher，但是当我尝试编译它时，由于我的内部子程序的缘故，我遭受了无法分类的声明错误。
我在'（''）'中列出了每个SUBROUTINE中使用的变量，但是我仍然收到错误。我认为这是一个非常简单的解决方法，但我似乎无法找到解决方案。
这是我的代码：
PROGRAM Assign_8
IMPLICIT NONE
CHARACTER * 750 ::输入
CHARACTER * 10 ::键
CHARACTER * 750 :: RepeatedKey
CHARACTER * 750 ::加密，解密
LOGICAL ::路径
字符* 10 ::验证
INTEGER ::代表，加密，解密，KeyInt，InputInt，MergeInt，UnmergeInt
WRITE（*，*）'你想加密还是解密文件？'
CALL Validation_Sub
$ b $ SUBROUTINE Validation_Sub（Path，Validation）
IMPLICIT NONE
READ（*，*）验证
SELECT CASE（验证）
CASE（'Encrypt'，'encrypt'）
WRITE（*，*）'您已选择加密文件'
Path = .TRUE 。
CASE（'Decrypt'，'decrypt'）
WRITE（*，*）'您已选择解密文件'
Path = .FALSE。
CASE DEFAULT
WRITE（*，*）'选择无效请选择加密或解密文件。'
IF（Path .EQV。 TRUE。）THEN
CALL Encrypt_Sub
ELSE IF（Path .EQV .FALSE。）THEN
CALL Decrypt_Sub
END IF
END SELECT
END SUBROUTINE
SUBROUTINE Encrypt_Sub（Input，Key，RepeatedKey，Encrypt，InputInt，KeyInt，MergeInt，Encrypted）
IMPLICIT NONE
$ b OPEN（1，FILE ='plaintext.txt'）
READ（1，'（A）'）输入
WRITE（* *）'请输入10个字符的关键词组（包括空格和标点符号）'
READ（*，*）键
RepeatedKey = REPEAT（键（1:10），75）
DO Encrypt = 1，LEN_TRIM（输入）
InputInt = IACHAR（输入（加密：加密））
KeyInt = IACHAR（RepeatedK ey（Encrypt：Encrypt））
MergeInt = InputInt +（KeyInt - 32）
IF（MergeInt> 126）THEN
MergeInt = MergeInt - 94
END IF
加密（加密：加密）= ACHAR（MergeInt）
END DO
OPEN（2，FILE ='EncryptionTest.txt'）
WRITE（2，'（A）'）加密
CLOSE（2）
子程序
$ b $ SUBROUTINE Decrypt_Sub（加密，密钥，重复密钥，解密，MergeInt，KeyInt，UnmergeInt，解密）
隐式无
OPEN（1，FILE ='EncryptionTest.txt'）
READ（1，'（A）'）加密
CLOSE（1）
WRITE（*，*）'请输入您的密钥短语'
READ（*，'（A）'）键
RepeatedKey = REPEAT（Key（1:10），75）
DO Decrypt = 1,750,1
MergeInt = IACHAR（Encrypted（Decrypt：Decrypt））
KeyInt = IACHAR（RepeatedKey（Decrypt：Decrypt））
UnmergeInt = MergeInt - （KeyInt - 32）
IF（UnmergeInt UnmergeInt = UnmergeInt + 94
END IF
Decrypt（Decrypt：Decrypt）= ACHAR（UnmergeInt）
END DO
OPEN（2，FILE ='DecryptionTest.txt'）
WRITE（2，'（A）'）解密
CLOSE（2）
结束子程序
END PROGRAM Assign_8
我回来的具体错误是： （b）>
SUBROUTINE Validation_Sub（Path，Validation）
1
>
IMPLICIT NONE
1
>意外的IMPLICIT NONE语句位于（1）
我怀疑IMPLICIT NONE错误是由于SUBROUTINE未被正确定义。
END SUBROUTINE
1
>期望在（1）
像以前一样，我怀疑这个我因为SUBROUTINE尚未定义。
这些错误会重复以下情况：
SUBROUTINE Encrypt_Sub
&
SUBROUTINE Decrypt_Sub
任何帮助将不胜感激，如果任何人都会在我的Vigenere Cypher代码本身中发现任何直接的错误，如果您能指出它是否没有问题，也将非常感激。解决方案
在你的子程序之前你缺少 CONTAINS 。
在未来的学习模块中，现在使用
CONTAINS ，使这些子程序在主程序中正常运行。
所以它应该看起来像
PROGRAM Assign_8
...
CALL Validation_Sub
CONTAINS
SUBROUTINE Validation_Sub（路径，验证）
END SUBROUTINE
...
END PRO GRAM Assign_8
So I've written a basic Vigenere Cypher in Fortran 90, however when I try to compile it, I am hammered with Unclassifiable Statement Errors due to my internal SUBROUTINES.
I have listed the variables used in each SUBROUTINE in '(' ')', but I am still getting back errors. I think it's a really simple fix, but I can't seem to find a solution to it.
Here is my code:
PROGRAM Assign_8
IMPLICIT NONE
CHARACTER*750 :: Input
CHARACTER*10 :: Key
CHARACTER*750 :: RepeatedKey
CHARACTER*750 :: Encrypted, Decrypted
LOGICAL :: Path
CHARACTER*10 :: Validation
INTEGER :: Reps, Encrypt, Decrypt, KeyInt, InputInt, MergeInt, UnmergeInt
WRITE(*,*) 'Do you wish to Encrypt or Decrypt a file?'
CALL Validation_Sub
SUBROUTINE Validation_Sub(Path, Validation)
IMPLICIT NONE
READ(*,*) Validation
SELECT CASE (Validation)
CASE ('Encrypt' , 'encrypt')
WRITE(*,*) 'You have selected to Encrypt a file.'
Path = .TRUE.
CASE ('Decrypt' , 'decrypt')
WRITE(*,*) 'You have selected to Decrypt a file.'
Path = .FALSE.
CASE DEFAULT
WRITE(*,*) 'Selection not valid please select to either Encrypt or Decrypt a file.'
IF (Path .EQV. .TRUE.) THEN
CALL Encrypt_Sub
ELSE IF (Path .EQV. .FALSE.) THEN
CALL Decrypt_Sub
END IF
END SELECT
END SUBROUTINE
SUBROUTINE Encrypt_Sub(Input, Key, RepeatedKey, Encrypt, InputInt, KeyInt, MergeInt, Encrypted)
IMPLICIT NONE
OPEN(1,FILE='plaintext.txt')
READ(1,'(A)') Input
WRITE(*,*) 'Please Enter a Key Phrase of 10 Characters (Including Spaces and Punctuation)'
READ(*,*) Key
RepeatedKey = REPEAT(Key(1:10),75)
DO Encrypt = 1, LEN_TRIM(Input)
InputInt = IACHAR(Input(Encrypt:Encrypt))
KeyInt = IACHAR(RepeatedKey(Encrypt:Encrypt))
MergeInt = InputInt + (KeyInt - 32)
IF (MergeInt > 126) THEN
MergeInt = MergeInt - 94
END IF
Encrypted(Encrypt:Encrypt) = ACHAR(MergeInt)
END DO
OPEN(2,FILE='EncryptionTest.txt')
WRITE(2,'(A)') Encrypted
CLOSE(2)
END SUBROUTINE
SUBROUTINE Decrypt_Sub(Encrypted, Key, RepeatedKey, Decrypt, MergeInt, KeyInt, UnmergeInt, Decrypted)
IMPLICIT NONE
OPEN(1,FILE='EncryptionTest.txt')
READ(1,'(A)') Encrypted
CLOSE(1)
WRITE(*,*) 'Please Enter Your Key Phrase'
READ(*,'(A)') Key
RepeatedKey = REPEAT(Key(1:10),75)
DO Decrypt = 1, 750, 1
MergeInt = IACHAR(Encrypted(Decrypt:Decrypt))
KeyInt = IACHAR(RepeatedKey(Decrypt:Decrypt))
UnmergeInt = MergeInt - (KeyInt - 32)
IF (UnmergeInt < 32) THEN
UnmergeInt = UnmergeInt + 94
END IF
Decrypted(Decrypt:Decrypt) = ACHAR(UnmergeInt)
END DO
OPEN(2,FILE='DecryptionTest.txt')
WRITE(2,'(A)') Decrypted
CLOSE(2)
END SUBROUTINE
END PROGRAM Assign_8
And the specific errors I am getting back are:
SUBROUTINE Validation_Sub(Path, Validation)
1
>Unclassifiable Statement at (1)
(Spacer)
IMPLICIT NONE
1
>Unexpected IMPLICIT NONE statement at (1)
I suspect the IMPLICIT NONE error is due to the SUBROUTINE not being defined properly.
END SUBROUTINE
1
>Expecting END Program statement at (1)
As before, I suspect this is because the SUBROUTINE has not been defined.
These errors repeat themselves for:
SUBROUTINE Encrypt_Sub
&
SUBROUTINE Decrypt_Sub
Any help would be greatly appreciated, if anyone does spot any immediate errors within my Vigenere Cypher code itself it would also be greatly appreciated if you could point them out if its no trouble.
解决方案
You are missing CONTAINS before your subroutine.
In the future learn modules, but now use CONTAINS to make those subroutines properly internal to the main program.
So it should look like
PROGRAM Assign_8
...
CALL Validation_Sub
CONTAINS
SUBROUTINE Validation_Sub(Path, Validation)
END SUBROUTINE
...
END PROGRAM Assign_8
