c ables for the adjoint calculations. All
c files are direct access files.
c
c Routines:
c
c o active_read_rl_loc - Basic routine to handle active read
c operations.
c o active_write_rl_loc - Basic routine to handle active write
c operations.

C !DESCRIPTION: \bv
c ==================================================================
c o Read an active _RL variable from file.
c The variable *globalfile* can be used as a switch, which allows
c to read from a global file. The adjoint files are, however, always
c treated as tiled files.
