i tried in compaq visual fortran 6.6
the file names can be long, and visual fortran knows the difference.
【在 bd 的大作中提到】
: 它对变量名的长度有限制吗？

我的是5。0，
其实我自己用小程序试过，好象区分的，总是有点不放心。
当初fortran77的语法是：变量名一般不超过6位，超过的只取前6位。

If you're using Fortran 77, the restriction is still there.
Even though your compiler allows you using more than 6 characters,
it's just the extension of your compiler, rather than the standard of F77.
If you're using Fortran 90, there is no restriction on the length
of the variable names. This is the standard that any F90 compiler
should comply with.

visual fortran默认是F90吧，其实我用的语法是F77的，但测试时发现确实可以区分6位
以上的。
