       Name: DTW4                                                    [Show more]
       Type: Variable
   Category: Text
    Summary: Flags that govern how justified extended text tokens are printed
  Deep dive: Extended text tokens
    Context: See this variable in context in the source code
 References: This variable is used as follows:
             * MESS uses DTW4
             * MT15 uses DTW4
             * TT26 uses DTW4


 This variable is used to control how justified text tokens are printed as part
 of the extended text token system. There are two bits that affect justified
 text:

   * Bit 7: 1 = justify text
            0 = do not justify text

   * Bit 6: 1 = buffer the entire token before printing, including carriage
                returns (used for in-flight messages only)
            0 = print the contents of the buffer whenever a carriage return
                appears in the token

 The default value is %00000000 (do not justify text, print buffer on carriage
 return).

 The flag is set to %10000000 (justify text, print buffer on carriage return)
 by jump token 14, {justify}, which calls routine MT14 to change the value of
 DTW4.

 The flag is set to %11000000 (justify text, buffer entire token) by routine
 MESS, which prints in-flight messages.

 The flag is set to %00000000 (do not justify text, print buffer on carriage
 return) by jump token 15, {left align}, which calls routine MT1 to change the
 value of DTW4.
