procedure Col_Check (N : Nat);

procedure Indent_Annull;
-- Causes following call to Write_Indent to be ignored. This is used when
-- a higher level node wants to stop a lower level node from starting a
-- new line, when it would otherwise be inclined to do so (e.g. the case
-- of an accept statement called from an accept alternative with a guard)
procedure Indent_Begin;
-- Increase indentation level
procedure Indent_End;

procedure Print_Eol;
-- Terminate current line in line buffer
procedure Process_TFAI_RR_Flags (Nod : Node_Id);
-- Given a divide, multiplication or division node, check the flags
-- Treat_Fixed_As_Integer and Rounded_Flags, and if set, output the
-- appropriate special syntax characters (# and @).
procedure Set_Debug_Sloc;
-- If Debug_Node is non-empty, this routine sets the appropriate value
-- in its Sloc field, from the current location in the debug source file
-- that is currently being written. Note that Debug_Node is always empty
-- if a debug source file is not being written.
procedure Sprint_Bar_List (List : List_Id);
-- Print the given list with items separated by vertical bars
procedure Sprint_Node_Actual (Node : Node_Id);
-- This routine prints its node argument. It is a lower level routine than
-- Sprint_Node, in that it does not bother about rewritten trees.
procedure Sprint_Node_Sloc (Node : Node_Id);
-- Like Sprint_Node, but in addition, in Debug_Generated_Code mode,
-- sets the Sloc of the current debug node to be a copy of the Sloc
-- of the sprinted node Node. Note that this is done after printing
-- Node, so that the Sloc is the proper updated value for the debug file.
procedure Write_Char_Sloc (C : Character);
-- Like Write_Char, except that if C is non-blank, Set_Debug_Sloc is
-- called to ensure that the current node has a proper Sloc set.
procedure Write_Discr_Specs (N : Node_Id);
-- Output discriminant specification for node, which is any of the type
-- declarations that can have discriminants.
procedure Write_Ekind (E : Entity_Id);
-- Write the String corresponding to the Ekind without "E_".
procedure Write_Id (N : Node_Id);
-- N is a node with a Chars field. This procedure writes the name that
-- will be used in the generated code associated with the name. For a
-- node with no associated entity, this is simply the Chars field. For
-- the case where there is an entity associated with the node, we print
-- the name associated with the entity (since it may have been encoded).
-- One other special case is that an entity has an active external name
-- (i.e. an external name present with no address clause), then this
-- external name is output.
function Write_Identifiers (Node : Node_Id) return Boolean;
-- Handle node where the grammar has a list of defining identifiers, but
-- the tree has a separate declaration for each identifier. Handles the
-- printing of the defining identifier, and returns True if the type and
-- initialization information is to be printed, False if it is to be
-- skipped (the latter case happens when printing defining identifiers
-- other than the first in the original tree output case).

function Write_Indent_Identifiers (Node : Node_Id) return Boolean;
-- Like Write_Identifiers except that each new printed declaration
-- is at the start of a new line.
function Write_Indent_Identifiers_Sloc (Node : Node_Id) return Boolean;
-- Like Write_Indent_Identifiers except that in Debug_Generated_Code
-- mode, the Sloc of the current debug node is set to point ot the
-- first output identifier.
procedure Write_Indent_Str (S : String);
-- Start a new line and write indent spacing followed by given string
procedure Write_Indent_Str_Sloc (S : String);
-- Like Write_Indent_Str, but in addition, in Debug_Generated_Code mode,
-- the Sloc of the current node is set to the first non-blank character
-- in the string S.
procedure Write_Name_With_Col_Check (N : Name_Id);
-- Write name (using Write_Name) with initial column check, and possible
-- initial Write_Indent (to get new line) if current line is too full.
procedure Write_Name_With_Col_Check_Sloc (N : Name_Id);
-- Like Write_Name_With_Col_Check but in addition, in Debug_Generated_Code
-- mode, sets Sloc of current debug node to first character of name.
procedure Write_Operator (N : Node_Id; S : String);
-- Like Write_Str_Sloc, used for operators, encloses the string in
-- characters {} if the Do_Overflow flag is set on the node N.
procedure Write_Param_Specs (N : Node_Id);
-- Output parameter specifications for node (which is either a function
-- or procedure specification with a Parameter_Specifications field)
procedure Write_Rewrite_Str (S : String);
-- Writes out a string (typically containing <<< or >>>}) for a node
-- created by rewriting the tree. Suppressed if we are outputting the
-- generated code only, since in this case we don't specially mark nodes
-- created by rewriting).
procedure Write_Str_Sloc (S : String);
-- Like Write_Str, but sets debug Sloc of current debug node to first
-- non-blank character if a current debug node is active.
procedure Write_Str_With_Col_Check (S : String);
-- Write string (using Write_Str) with initial column check, and possible
-- initial Write_Indent (to get new line) if current line is too full.
procedure Write_Str_With_Col_Check_Sloc (S : String);
-- Like Write_Str_WIth_Col_Check, but sets debug Sloc of current debug
-- node to first non-blank character if a current debug node is active.
procedure Write_Uint_With_Col_Check_Sloc (U : Uint; Format : UI_Format);
-- Write Uint (using UI_Write) with initial column check, and possible
-- initial Write_Indent (to get new line) if current line is too full.
-- The format parameter determines the output format (see UI_Write).
-- In addition, in Debug_Generated_Code mode, sets the current node
-- Sloc to the first character of the output value.
procedure Write_Ureal_With_Col_Check_Sloc (U : Ureal);
-- Write Ureal (using same output format as UR_Write) with column checks
-- and a possible initial Write_Indent (to get new line) if current line
-- is too full. In addition, in Debug_Generated_Code mode, sets the
-- current node Sloc to the first character of the output value.
