FORMATFORMEMORY-READ:

PRINT# file#, "M-R:" CHR$(low byte of address) CHR$(high byte)

(no abbreviation!)

The next byte read using the GET# statement through channel# IS, the

error channel, will be from that address in the disk controller's memory, and

successivebytes will be from successivememory locations.

Any INPUT# to the error channel will give peculiar results when you're

using this command. This can be cleared up by any other command to the disk

(besides a memory command).

PROGRAM TO READ THE DISK CONTROLLER'S MEMORY:

10OPEN15,8,15

20 INPUT "LOCATION PLEASE"; A

30 AI= INT(A/2S6): A2= A- Al *256

40 PRINT# IS, "M-R:" CHR$(A2) CHR$(AI)

SOFOR L=I TO 5

60 GET# IS, A$

70 PRINT ASC(A$+CHR$(O));

80 NEXT

90 INPUT "CONTINUE";A$

100 IF LEFT$(A$,I) ="Y" THEN SO

110 GOTO 20

MEMORY-WRITE

The MEMORY-WRITEcommandallowsyou to write up to 34 bytesat a

time into the disk controller's memory. The MEMORY-EXECUTEand USER

commands can be used to run this code.

FORMAT FOR MEMORY-WRITE:

PRINT# file#, "M-W:" CHR$(low address byte) CHR$(high address byte)

#-of-characters; byte data

PROGRAM TO WRITE A "RTS" TO DISK:

I0 OPENIS, 8, IS. "M-W:" CHR$(O)CHR$(S); I; CHR$(96)

20 PRINT# IS, "M-E:" CHR$(O)CHR$(I 9): REM JUMPSTO BYTE, RETURNS

30 CLOSE IS -

MEMORY-EXECUTE

Any routine in the DOSmemory, RAMor ROM, can be executed with the

MEMORY-EXECUTEcommand.
