bc: Pseudo Statements

 
 4.1 Pseudo Statements
 =====================
 
 These statements are not statements in the traditional sense.  They are
 not executed statements.  Their function is performed at "compile" time.
 
 'limits'
      Print the local limits enforced by the local version of 'bc'.  This
      is an extension.
 
 'quit'
      When the 'quit' statement is read, the 'bc' processor is
      terminated, regardless of where the 'quit' statement is found.  For
      example, "if (0 == 1) quit" will cause 'bc' to terminate.
 
 'warranty'
      Print a longer warranty notice.  This is an extension.
