So to do this you will need to understand the MAPDL language (see MAPDL command reference for details).

 

Then 

Look at the ds.dat file which is the input file going to the apdl solver and that was created by mechanical.

 

In there (ds.dat) you should find some loads defined by sf or sfe commands - then look these commands up in the command reference in the help manual and try to understand them - once you do you can add command snippets in mechanical trying and as you say use parameters with their arguments ARG1,....

 

Hope this helps
