Fortran prolem

[Richard Allen]

Im using a well patched 11i (11.11) L2000 machine and compiling old fortran programs.
I get the following error at runtime on many of them:

*** FORTRAN I/O ERROR 900: ERROR IN FORMAT
FILE: /vm/vmgogn/rennsli/205/0020577.wol, UNIT: 1

( 7) 0x000023a8 $START$ + 0x178 [/vm/HP-UX/bin/nysko]

Even Google fails me here so I need your help :)

Thanks in advance :)

It might be helpful to know the format and the variable in question, in leswol?
