DOS XL Bugs and Fixes
---------------------
BUG: The patch to convert version
2.30 to version 2.30p in our Spring
1984 newsletter didn't work.
FIX: Run the following program and
then use INIT with the "Write DOS.SYS
Only" option to write out the patched
DOS. Make sure that you don't have
DOSXL.SYS (either .SUP or .XL
version) active when you do this.
100 READ CNT:IF CNT=0 THEN END
110 READ START
120 FOR ADDR=START TO START+CNT-1
130 READ BYTE:POKE ADDR,BYTE
135 NEXT ADDR
140 GOTO 100
150 DATA 3,5481,32,1,21
160 DATA 29,5377,141,217,22,169,16
170 DATA 141,23,22,169,23,141,24,22

190 DATA 12,0,169,21,141,13,0,96
200 DATA 1,7425,112,0
BUG: INIT does not work if you use
drive numbers 4 through 8.
FIX: Run the following program:
10 OPEN #1,12,0,"D:INIT.COM"
20 FOR I=1 TO 116 : GET #1,C : NEXT I
30 PUT #1,ASC("9") : CLOSE #1
