Save As.bas added to Code Library

Forums: 

Save As.bas added to Code Library under System; it might come in handy if you keep a copy in SB work area, folder or desktop.

Maybe this is start of an external menu system.

ISOdate.bas added to Code Library under System. ISO format YYYY-MM-DD is nice for sorting by date, here 2 digits always for D and M, 4 for Y, total length is 10.
