Text: DTW1

       Name: DTW1                                                    [Show more]
       Type: Variable
   Category: Text
    Summary: A mask for applying the lower case part of Sentence Case to
             extended text tokens
  Deep dive: Extended text tokens
    Context: See this variable in context in the source code
 References: This variable is used as follows:
             * DETOK2 uses DTW1
             * MT13 uses DTW1
             * MT2 uses DTW1


 This variable is used to change characters to lower case as part of applying
 Sentence Case to extended text tokens. It has two values:

   * %00100000 = apply lower case to the second letter of a word onwards

   * %00000000 = do not change case to lower case

 The default value is %00100000 (apply lower case).

 The flag is set to %00100000 (apply lower case) by jump token 2, {sentence
 case}, which calls routine MT2 to change the value of DTW1.

 The flag is set to %00000000 (do not change case to lower case) by jump token
 1, {all caps}, which calls routine MT1 to change the value of DTW1.

 The letter to print is OR'd with DTW1 in DETOK2, which lower-cases the letter
 by setting bit 5 (if DTW1 is %00100000). However, this OR is only done if bit
 7 of DTW2 is clear, i.e. we are printing a word, so this doesn't affect the
 first letter of the word, which remains capitalised.
