__FB_UNIQUEID__

Intrinsic define (macro) performed by the compiler.

Syntax
   __FB_UNIQUEID__( stack-id )

Parameters
   stack-id
      the name of the stack to access

Description
   Gets the identifier at the top of stack identified by stack-id (the size 
   of the stack is not modified).
   (__FB_UNIQUEID_PUSH__ allows to push a new unique identifier on to the 
   stack, and __FB_UNIQUEID_POP__ allows to pop an identifier off of the 
   stack)

   Note:
      - The 'stack-id' name itself is a separate namespace from all other 
      symbols.
      - The stack can only contain 'unique identifiers'.
      - 'unique identifier' is a name of an fb symbol that is unique to the 
      module, so does not conflict or shadow other symbol names ('unique 
      identifier' will have the form 'LT_xxxx' as a name so it might not be 
      completely unique).
      - fb uses the form 'LT_xxxx' internally for labels, symbols, temp 
      variables, etc (so should avoid naming fbc symbols of this form for 
      any fbc program since version 0.0).

   __FB_UNIQUEID__ simply expands to unquoted text. So the name, for 
   example 'Lt_0004', can be used wherever an fb symbol is required (a 
   variable, procedure name, type name, etc.).
   __FB_UNIQUEID__ returns an unquoted empty string when the stack is empty 
   or has never been filled.

Example
   __FB_UNIQUEID_PUSH__( stk )
   #print __FB_UNIQUEID__( stk )

      __FB_UNIQUEID_PUSH__( stk )
      #print __FB_UNIQUEID__( stk )

         __FB_UNIQUEID_PUSH__( stk )
         #print __FB_UNIQUEID__( stk )
         __FB_UNIQUEID_POP__( stk )

      #print __FB_UNIQUEID__( stk )
      __FB_UNIQUEID_POP__( stk )

   #print __FB_UNIQUEID__( stk )
   __FB_UNIQUEID_POP__( stk )
