例程名称在Fortran 90中的最大长度 [英] Routine name maximum length in Fortran 90

问题描述

有人知道Fortran 90中例程名称和变量名称的最大长度吗?

Does anyone know if there is a maximum length for routine names and variable names in Fortran 90?

推荐答案

是的，Fortran标准定义了事物名称(包括例程和变量)的最大长度.在Fortran 90/95中，最大长度为31个字符，在Fortran 2003中，现在为63个字符.在早期版本中，它只有6个字符.您的编译器可能允许(非标准)更长的名称.

Yes, the Fortran standards define a maximum length for names of things, including both routines and variables. In Fortran 90/95 the maximum length was 31 characters, in Fortran 2003 it is now 63 characters. In earlier versions it was as short as 6 characters. Your compiler may allow (non-standard) longer names.
