I am not sure I understand what you mean.
If what you want to do is save the visa aliases you are using, then simple write them to a file.
If what you would like to do is set up what aliases some of the resources use, you can either use MAX or you can edit the wisaconf.ini file. THis is where the alieas are saved in this format
Alias0 = "'LPT1','ASRL10::INSTR'"
Alias1 = "'COM2','ASRL2::INSTR'"
Alias2 = "'COM1','ASRL1::INSTR'"
As far as the resource manager I am not sure what you mean.
