CP/M Disk change error on drive x
.sp
The disk in the drive indicated by the variable "x" is 
not the same disk the system logged in previously.  When the 
disk was replaced you did not enter a CTRL-C to log in the 
current disk.  Therefore, when you attempted
to write to, erase, or rename a file on the current disk, the BDOS set the
drive status to read-only and warm booted the system.
The current disk in the drive was not overwritten.  The drive status 
was returned to read-write when the system was warm booted.  Each time a 
disk is changed, you must type a CTRL-C to log in
the new disk.

1) The file is not a valid executable command file.  Ensure that you are 
requesting the correct file.  This error can occur
when you enter the filename before you enter the command for a 
utility.  Check the appropriate section of this manual or the 
CP/M-8000 Operating System User's Guide for the correct
command syntax before you reenter the command line.  If you are trying to run
a program when this error occurs, the program file may
have been corrupted.  Reassemble or recompile the source file 
and relink the file before you reenter the command line.

2) The program is too large for the available memory.  Add more memory boards 
to the system configuration, or rewrite the 
program to use less memory.  
.sp
.ti -3
3) The program is linked to an absolute location in memory that cannot be 
used.  The program must be made relocatable, or linked to a usable 
memory location.  The BDOS Get/Set TPA Limits Function (63) returns 
the high and low boundaries of the memory space that is 
available for loading programs.

3) The command file has been corrupted.  Reassemble or recompile the source 
file 
before you reread it into memory with a Load for Execution (E) or 
Read (R) command, as appropriate.  If the problem persists, use the 
debugging commands in DDT-8000 to look for an error in the program 
that causes it to overwrite itself.  Refer to the section in this manual 
on DDT-8000 for a complete description of the DDT-8000 commands and
