Two standard commands in your typical macro shell. They save ad restore the symbol table, with expansions, on the disk. The actions have nothing to do with operting configurations, paths, cmputer setting, or any of that spaghetti; it just saves the macro expansions and names as strings of characters with pointers, normally as lines of text/
Geeks and professors sometimes forget the basics, they get into the machine details and neglect to mention the macro shell is simply a text manager, it knows nothing else.
Burt saving and restoring removes a big headache for me, I am out of the lab making the application work. A new environment. The scientist usually generates a white paper and leaves behind a huge pile of spaghetti, can't do that anymore.
What is spaghetti? It is a pile of random, often redundant, computer statements that do one thing at one specific instance for one person and has an audience of one, it is pure lab code.
