To load the Command Processor from within other software, give the command equivalent to the BASIC "DOS" command, usually something like "EXIT" or "RETURN TO DOS". Before you load the Command Processor, insert a disk that contains the Command Processor program into disk drive #1 (if using the disk drive number redirection feature of DOS 4 then the CP program must go into logical drive #1, not physical drive
#1). If you attempt to load the Command Processor without first inserting such a disk, the computer will "freeze". If this happens, press BREAK and another attempt will be made to load the Command Processor. The CP menu is constructed by reading the directory of disk drive #1 and listing all files whose names end in the extender ".COM". (If disk drive number redirection is being used, the CP reads the directory of logical drive #1, not physical drive ##) maximum of sixteen such files can be listed.

2. A four-byte header in which the first two bytes give the address where the first byte of the data block goes, and the last two bytes
give the address where the last byte of the data block goes.
