Description

With statements perform an action, while allowing the fields of specified record variables to be referencing using their field identifiers only. With statements include the following:

• A record-variable-list, which contains one or more record variables.
• A statement which specifies the action to perform. Inside this statement the fields, in any of the record variables in the record-variable-list, can be referenced using their field identifiers only.

For example give the following type and variable.

   type
     student = record
     name : string;
     address : string;
     grade : integer;
     end;

   var
     s : student;

then the following with statement

   with s do
      begin
         name := 'John';
         address := 'main street';
         grade := 20;
      end

is equivalent to

   begin
      s.name := 'John';
      s.address := 'main street';
      s.grade := 20;
   end

Since some record types can contain other record types you can have nested with statements like the following:

   with record1 do
      with record2 do
        with record3 do
           statement

or you can use the following shorthand which does the same thing

  with record1, record2, record3 do
     statement

Syntax

(NOTE: for clarity some parts of the syntax are omitted, see Irie Pascal Grammar for the full syntax):

   with-statement = 'with' record-variable-list 'do' statement

   record-variable-list = record-variable { ';' record-variable }
