Embedded matlab block as a parameter - not an input (without "ports and data manager")

Hello,
When using an embedded Matlab block within Simulink, I would like to make the use of parameters more transparent by including definition of ports in the function i.e
function [ ...
... % Signals controlling stimulus
output_arg1 ,...
output_arg2 ]...
= Sequencer( ...
... % From Test Bench
time_in ,...
stop_time ,...
fixed_step_size ,...
... % From UUT
input_arg1 ,...
input_arg2)
% Function code
end
Where "fixed_step_size" is not an input port to the block but instead takes the value from the workspace - the value in the work space will not change over the duration of the simulation.
At the moment I am using the "ports and data manager" but this is not obvious when reviewing code.
so the question is: Is there a way to get a workspace parameter from the workspace - within the Matlab code, without using the ports and data manager?
Many thanks!
Dave

sorry, I just found this:
coder.extrinsic('evalin')
fixed_step_size = evalin('base', 'fixed_step_size');
