APPENDIX TWELVE



62026          F24A           GETCHAR
     New location for the "get character" routine (used to be at
     63038). If you use the routines for screen display in Machine
     Language for Beginners, you'll have to change this address for
     proper XL operation.

62128          F2B0           OUTCHAR
     New location for the "put character" routine. See the note in
     62026. Several programs make use of an illegal call to the "get
     character" and "put character" routines, previously at 63038
     and 63140 ($F63E and F6A4), now at locations 62026 and 62128
     ($F24A and $F2B0), respectively. You may be able to correct
     some problems in your software by searching for and replac-
     ing the older vectors with the new locations.
