Error Messages
Debug Manual—421921-003
A-17
68
68
Cause. An attempt was made to clear a breakpoint using the C command, but no
code address was specified. The C command without an address can be used only if
the current program location is at a breakpoint.
Effect. The command is not executed.
Recovery. Specify an address to the C command, or use some other option available
in the C command syntax.
69
Cause. The specified address to the C command could not be found in the breakpoint
table.
Effect. The command is not executed.
Recovery. Use the B or B* command to see the contents of the breakpoint table.
70
Cause. The specified output base was not acceptable for the indicated command. The
acceptable base set for the equal (=) command are as follows: A, B, H, E, N, O, R, T,
#, and %. Other commands have more restricted sets. For more information on the
description of the Debug commands, see Debug Commands on page 4-1.
Effect. The command is not executed.
Recovery. Specify the appropriate base and try again.
71
Cause. The specified value for the = command did not fit into 16 bits. Converting a
value to E register requires the value to fit in 16 bits.
Effect. The command is not executed.
Recovery. Make sure that the value that you specified fits into 16 bits.
Need code address to find and clear breakpoint.
Breakpoint matching address not found.
Invalid conversion base.
Base E not allowed when value cannot be stored in 16-bits.
