environmental variables      Overview     environmental variables




The  _e_n_v_i_r_o_n_m_e_n_t is  a set  of  information that  is read  by all
programs that  run on  your system.  It  consists of one  or more
_e_n_v_i_r_o_n_m_e_n_t_a_l _v_a_r_i_a_b_l_e_s that  you set.  For example, when you set
the environmental variable  PPAATTHH, you tell COHERENT that you wish
to  pass  this  information  to  all  programs  on  your  system,
including COHERENT itself.

By changing  the environment,  you can  change the way  a command
works without  rewriting any commands that  you may have embedded
in batch files, scripts, or mmaakkeeffiillees.

COHERENT uses  the following  environmental variables to  set its
environment.  The programs that you write may use others that you
define yourself, if you wish.
