In SKILL，the default namespace is the namespace that is opened at the start of the SKILL interpreter. The symbols from the default namespace can be referenced with their full names, such as IL:::<symbol_name> or just by their names such as <symbolname> since there is no way to change the current namespace.
A SKILL programmer often uses the same name for different p
purposes when working on a large project with different programmers.Usually this problem is solved by using naming conventions or adding prefixes to function names, such as leCreateRect,dbCreateRect,rodCreateRect,and geCrerateRect. SKILL provides a language mechanism called namespace to separate these symbols, so that a symbol with the same name can exist in several namespaces.
