is this not enough to tell you why?
use mkstemp instead of tempname,

Unix server?
linux server?
seg fault generally is due to mistaken usage of pointers

In Fortran, it's normally due to an access to an array element beyond
the bounds, i.e. misuse of the pointers.

可是f95有了叫指针的指针类似物
f77里不叫指针的指针怎么指到外面去？

不严格的讲， 数组的下标就可以叫指针
你定义了一个A[20]
调用的时候用到了A[I]， I不小心设成了30， 不就指到外面出了吗？

i guess that reference won't return anything except error in fortran

Recently have to use a Fortran code written by another folk. He
used command-line-arguments a lot. Like this
character*80 cint
...
getarg(1, cint)
read(cint, *) number
...
Are these "getarg" and "read(cint, *)" standard fortran syntax, or
just dialect used by some compilers?
