Error Read in data in user-subroutine

Ingear

Hi, In bcdefi.f, I inclueded the following code, but I received error message. The code:

open (85,file='data.dat',status='unknown')

do 102 i=1,NVX

read (85,*) II(i),xx(i),yy(i),zz(i) 102 continue

close (85)

The error: ../ufile/linux64_2.4-itanium-efc_7.1-glibc_2.2.4-dso-debug/libstarusr.so: undefined symbol: for_open

Does anyone know what went wrong ? Thank You.
