[gradsusr] Fortran Code

[Konstantinos Eleftheratos]

Hi Ali

 

You define your file 'u' as integer which is wrong. It has to be defined as
character.

Integers are numbers, but file names are characters.

 

Something else

In the command,  read(u,*) n , 

You have not defined n and this may cause other error. 

 

Good luck,

Kostas Eleftheratos

real x(nmax), y(nmax), z(nmax)

open (u, FILE='points.dat', STATUS='OLD')

read(u,*) n

if (n.GT.nmax) then

write(*,*) 'Error: n = ', n, 'is larger than nmax =', nmax

goto 9999
