# MFC.. commands are used to communicate with a Filter Changer
#
# base_command    - a string to be output to the filter changer
#
# appended_value  - this may be a constant, variable label, or computed
#                   expression - it will be append to the base_command string
#
# return variables - the return variables are defined in the response
#                    table of the /specs/mfc.cfg file
#                    (See /specs.def/mfc.cfg)

   'set something to'   my_var           
   
# NOTE:
#     when the 'base_command' is 'set_counters' the 'appended_command' is 
#     a list of the variables that contain the filter count that should be
#     set. The variables are specified as follows:
#
#  'set_counters        vrbl_a vrbl_b vrbl_c vrbl_d vrbl_e
#
#        where:
#          vrbl_a - the variable containing the number of filters in Canister A
#          vrbl_b - the variable containing the number of separators in Canister A
#          vrbl_c - the variable containing the number of filters in Canister C
#          vrbl_d - the variable containing the number of separators in Canister A
#          vrbl_e - the variable containing the number of filters in the holder
