Allow a subprogram to change a dummy argument that is a constant. This option is provided only to allow legacy code to compile and execute without a runtime error.Without -copyargs, if you pass a constant argument to a subroutine, and then within the subroutine try to change that constant...
Aninternalfile is an object of typeCHARACTERsuch as a variable, substring, array, element of an array, or field of a structured record. Internal fileREADcan be from aconstantcharacter string. I/O on internal files simulates formattedREADandWRITEstatements by transferring and converting data from ...
CHARACTER (len=*), INTENT(IN)::STRING1 使用*表示长度即可。因为没有必要在编译时必须知道字符串长度。 小问题 不要在子例程中加入STOP语句,否则程序会“神秘终止”。 正确方法是对可能存在的错误进行检测。使用IF语句进行检测,采取相应操作。例如返回error=0。 模块共享数据 模块,使用MODULE声明。 MODULE shared...
转载自https://iowiki.com/fortran/,在此基础上做了一些补充。 Fortran - Overview Fortran,源自公式翻译系统,是一种通用的命令式编程语言。 它用于数字和科学计算。 Fortran最初由IBM在20世纪50年代开发用于科学和工程应用。 Fortran统治了这个编程领域很长一段时间,并且因为高性能计算而变得非常流行。
Details concerning environment-specific values and defaults and system-specific features or limitations are presented in the release notes delivered with the PGI Visual Fortran. Conventions This guide uses the following conventions: italic is used for emphasis. Constant Width is used for filenames, ...
adjustl的函數值是把string的首部空格調到尾部,調右函數同理。例如adjustl(‘abc’)=‘abc’adjustr(‘abc’)=‘abc’6.字元與字元序號相互轉化函數(1)字元向字元序號轉化函數其一般形式為:ichar(ch)和iachar(ch)其中ch是長度為1的字元型常量和變數。其函數的結果值為字元在相應處理系統中的字元序號,例如...
fortran常见错误代码 fortran常见错误代码 If you have installed the Parallel Software Environment and compiled a program for parallel execution, additional messages specific to parallel execution may appear (see the DIGITAL High Performance Fortran 90 HPF and PSE Manual).
Constant Width is used for filenames, directories, arguments, options, examples, and for language statements in the text, including assembly language statements. Bold is used for commands. [ item1 ] in general, square brackets indicate optional items. In this case item1 is optional. In the...
(1): Not a Fortran-specific errorFOR$IOS_NOTFORSPE. An error in the user program or in the RTL was not a DIGITAL Fortran 90-specific error and was not reportable through any other DIGITAL Fortran 90 run-time messages. If you call ERRSNS, an error of this kind returns a value of 1...
