RAMP_DYNAMIC

# ramp a variable with dynamic evaluation of the end target and ramp
# rate when they are expressed as a variable or computed expression
#
# This functions identically to the @RAMP capability, except that the
# end and rate are dynamically re-evaluated every FAS interval until

@RAMP_DYNAMIC
   #variable      start          end         rate        termination
