DO
Reexecutes a command from the command stack.
Syntax
DO [cmd_string ]
DO [history_index]
DO, entered alone, reexecutes the most recent command.
Parameters
cmd_string Execute the most recent command in the history stack
that commences with cmd_string. For example, do wh
could be used to match the most recent WHILE statement.
history_index The history stack index of the command that is to be
executed.
A negative index can be used to specify a command
relative to the current command. For example, -2
implies the command used two commands ago.
Examples
%cmdebug > do w
%cmdebug > wl 2+4
%6
Execute the most recent command that started with "w".
Limitations, Restrictions
Upon initial entry into System Debug, the command stack is empty, since
no prior command has been executed. If the DO command is entered as the
first command, an empty command is reexecuted. This is effectively the
same as entering a blank line.
The MPE XL command interpreter allows an edit string to be specified on
the DO command line. This feature is not supported in System Debug.
CAUTION The output format of all System Debug commands is subject to
change without notice. Programs that are developed to
postprocess System Debug output should not depend on the exact
format (spacing, alignment, number of lines, uppercase or
lowercase, or spelling) of any System Debug command output.
