Printer

 GetScopeName
 get name of current enclosing procedure or module

 Calling Sequence Printer:-GetScopeName()

Parameters

 Printer - Printer module

Description

 • When called during the printing of intermediate code, the GetScopeName command returns the Name or GeneratedName corresponding to the name of the innermost enclosing procedure or module. For example, during the printing of a procedure body, GetScopeName returns the procedure's name.
 • If the enclosing scope does not have a name associated with it (for example, when the input is a single expression or a computation sequence) then NULL is returned.

Examples

Define a sample language GetScopeNameExample, using GetScopeName to obtain the name of a procedure during the printing phase.
