I'm not exactly sure what you mean. If you mean that you just want to enter a number, like 1,2,3, etc., then your sheet naming for the layouts much be consistent. The reference for the hyperlink is entirely based on the sheet tab name. So if all your sheets are named for example "page 1", "page 2", "page 3", etc. then you can determine the correct layout from the name.
BTW - the HYPERLINK command can do this without the need for an AutoLISP routine if you are just doing a random layout, presenting all the layout names is a list, and even named views within each layout.
