DESCRIPTION
The Command window issues debugger commands. It is one of the four primary windows. The other primary windows are Status, Source, and Log. In Command Window the Command window is identified by the Cdebug: prompt on the bottom line. Normally the Command window is displayed as shown, without a border and on the bottom line of the display. Like all the primary windows, the Command window is always open, even when it is obscured by an overlying window. Therefore, for purposes of the window command, it is a class 1 window. See window.

Issuing commands The Command window has two fields: a protected field that is used to display the Cdebug: prompt and a nonprotected command entry field. Debugger commands are typed into the command entry field, which starts immediately to the right of the Cdebug: prompt. You issue the command when you press the ENTER key. If a command is too long for the window, you can type it into the Log window by using a backslash for continuation.

Recalling commands As you issue commands, they are maintained by the debugger in a circular list. However, issuing the same command more than one time in succession results in only one copy of the command being maintained in the list. You can cycle through the list by using the window scroll < > up (PF19) and window scroll < > down (PF20) commands. You can recall previously issued commands by pressing the ENTER key. You can change recalled commands by typing over them before they are issued.

The previously issued commands are accessed in the order they were issued; as the list fills up, the oldest commands are deleted. You can use the window clear command to clear this list. The number of commands maintained in the circular list depends on the amount of memory that is allocated for the Command window. (The amount of memory that is allocated for window buffers cannot be changed during a session.) Each command requires one byte of storage for each character in the command plus three bytes for overhead information. You can specify the amount of memory that is used for this list with the window memory command.
