writing the bytes into the text buffer ram 16 this is then followed by a look up of bytes two and three adding the overlay data and writing to the text buffer ram 160 this is then followed by looking up byte 4 162 after looking up word 2 the question is asked whether the proportional spacing flag has been set 164 if there is to be proportional spacing a special fetch width is added to byte 4 166 and the proportional spacing flag is cleared following this or if there is space justification byte 4 is written into the text buffer ram 168 following this the text buffer pointer is incremented 170 and then the line length counter is incremented 172 following this the next ascii data character is read 130 referring now to fig6 the escape subroutine 136 will now be described when an escape flag 134 is found the next ascii data character is read 174 after this a proportional spacing inquiry is made 176 if proportional spacing is called for the space width is obtained 178 and the special fetch width is set 180 after this is completed a blank character is forced 182 and the.
