8 COMMANDS

8.1 General information

Commands to Xplor8 to carry out monitoring, debugging and loading operations are typed in to the

Command Edit Box at the lower left-hand corner of the main form. When the Enter or Return key is

pressed, the command is copied to the command history list in the window above the edit box. It does

not matter where the cursor is in the command line when the Enter key is struck, provided that the

command line edit box has focus. Each of the available commands is allocated a separate page in this

manual with a full description of its use and limitations, and a summary of all the commands is given

in Appendix C. Note also these points:

• If a syntax error is made in typing the command, Xplor8 echoes the command to the history

window with the addition of an explanatory message. In the following example of a mis-typed

List command, 008G is not a valid hexadecimal number:

L 0080 008G <-- Argument(s) not recognized

See the summary of Command Line Errors in Appendix E on page 79 for details of the

possible messages.

• Previously issued commands may be recalled by using the up and down arrow keys, and then

edited. Previous commands may also be reused by clicking or double-clicking on a line in the

command history list. When commands are recalled, they are transferred to the command line

edit box minus any comments, so that they may be corrected if necessary.

• Hitting the escape key clears the command line.

• The default number system for commands is hexadecimal (except for the specification of the

number of repeats - see, for example, the Unassemble command, page 62). However, decimal

and binary notation may also be used: precede a decimal number by a '#' symbol, and a binary

number by '%'. There is no need to prefix hexadecimal numbers with the dollar sign, although

it is not an error to do so. Leading zeros are optional. The following commands are identical:

L 0080 8F

L $0080 $008F

L #128 %10001111

• Commands may be typed in upper or lower case; it makes no difference as they are converted

to upper case before being parsed. The following commands are identical:

L FFF0 FFFF

L fFf0 fffF

• Command elements may be separated by one or more spaces or by a single comma, or a

mixture of the two. The following commands are identical:

L,0080,008F

L 80 8F

1 2 ... 35 36 37 38 39 40 41 42 43 44 45 ... 99 100
