       Type: Subroutine
   Category: Text
    Summary: Switch to standard tokens in Sentence Case
  Deep dive: Extended text tokens

    Context: See this subroutine in context in the source code
 References: This subroutine is called as follows:
             * JMTB calls MT6




 This routine sets the following:

   * QQ17 = %10000000 (set Sentence Case for standard tokens)

   * DTW3 = %11111111 (print standard tokens)



.MT6

 LDA #%10000000         ; Set bit 7 of QQ17 to switch standard tokens to
 STA QQ17               ; Sentence Case

 LDA #%11111111         ; Set A = %11111111, so when we fall through into MT5,
                        ; DTW3 gets set to %11111111 and calls to DETOK print
                        ; standard tokens

 EQUB $2C               ; Skip the next instruction by turning it into
                        ; $2C $A9 $00, or BIT $00A9, which does nothing apart
                        ; from affect the flags
