4.3. The Prompt
Some commands apply only to an axis or task (for example, the command
“PARMGET A” retrieves axis parameters). The user does not specify the task or axis for
these, instead the default axis or task is used. Either the default task or the default axis is
shown in the prompt preceding the command line. Use the TK and AX commands to
change the default task or axis. If the user does not specify a task or axis as an argument
to these commands, they simply switch the prompt to the default axis or task. View the
following series of commands for an example.
Prompt and command are... Defaults after command executed are....
axis 1, task 1
AX1>TK 4 axis 1, task 4
TK4>AX 16 axis 16, task 4
AX16>TK axis 16, task 4
TK4>AX axis 16, task 4
AX16>
4.3.1. Entering Commands
The command line is the line the cursor is on or the line the user is currently entering text
on. Alphabetic keystrokes (a to z, 0 to 9, ”-”, ”+”, ”.”) result in the corresponding
character being echoed on the command line and the cursor moving one character to the
right. Non-alphabetic keystrokes (i.e. “$”,”#”, Esc) are considered special characters and
may or may not be echoed. Also, the characters “_”, “\”, and “:” are considered alphabetic
and may be used in filenames. The case of alphabetic characters are ignored, lowercase
characters are echoed back as upper case. After the command is fully entered, the user can
hit the enter (return) key to execute the command.
As the user types, the status line will display all AerDebug commands that match the
current text. For example, if TSK has been typed on the command line, the status line will
display: “TSKASSOC, TSKDEASSOC, TSKINFO...” which are all valid AerDebug
commands starting with TSK.
If the text on the line matches only one valid command, then a single line description of
the command appears to the right of the command. For example, if TSKA is on the
command line, then “TSKASSOC - Associates program with current task...” appears on
the task line.
Once the text on the command line matches a single valid command, the user does not
need to type the rest of the command. For example, “TSKA” or “TSKASS” or
“TSKASSOC” are all equivalent.
In most cases, if the user provides an invalid parameter and hits return, AerDebug will
reject the return (not execute anything) and print an error message in the status bar. For
example, if the user types “AX 44” and hits return, Aerdebug will ignore the return key
because 44 is not a valid axis.
