Displays the contents of the command line history stack. You may specify the format in which the listing appears, and whether it appears on $STDLIST or in a file. (Native Mode)

Syntax

LISTREDO [START=m] [;END=n] [;OUT=outfile] [;{ ABS REL UNN }]

NOTE: This command follows the optional MPE/iX command line syntax. Refer to "Optional Format for MPE/iX Commands" at the beginning of this chapter.

Parameters

START or END

Specifies the range of commands to be displayed. Table 5-3 “History Stack Ranges” illustrates the effect of various START or END definitions.

Table 5-3 History Stack Ranges

StartEndEffect
(omitted)(omitted)Lists all commands in the redo stack.
mnLists commands m through n.
m(omitted)Displays commands m through the last command in the stack.
(omitted)nDisplays the stack from the first command through command n.

 

If m and n are negative values, they refer to relative command numbers (relative to the most recent command, which is -1). If m and n are positive, they refer to absolute command numbers (the order in which they were entered). To display a single line, m must equal n.

REL

Displays the commands in their relative sequence (from -m to -1), where -1 denotes the most recent command in the stack.

ABS

Displays the commands in their absolute order (the order in which they were entered). ABS is the default.

UNN

Suppresses numbering of the commands during display.

outfile

Sends the listing to a disk file named outfile instead of to the default, $STDLIST. New disk files are created TEMP. File equations are ignored, unless outfile is preceded by an asterisk (*). You must use a file equation to overwrite a permanent file.

Operation Notes

The LISTREDO command displays the contents of the REDO command line stack. By default, the display order is from the earliest command to the most recent command. Before any command line is displayed, anything resembling a lockword is blanked out. However, any lockwords remain active and available for editing through the DO and REDO commands.

Use

This command is available in a session, job, or in BREAK. It is not available from a program. Pressing Break aborts the execution of this command.

Examples

If three commands are written to the REDO stack and the third command is LISTREDO, the display appears as:

 1) COMMANDONE
2) COMMANDTWO
3) LISTREDO

If the third command were LISTREDO ;REL, the display appears as:

 -3) COMMANDONE
-2) COMMANDTWO
-1) LISTREDO ;REL

To create a permanent disk file called CMDFILE containing the output from LISTREDO, enter:

 BUILD CMDFILE;REC=-80,,,ASCII;DISC=9
FILE LIST=CMDFILE,OLD
LISTREDO -10,-2;OUT=*LIST;UNN

CMDFILE contains a listing of nine command lines, but without the command number; -10 is 9 lines distant from the most recent command; -2 is one line distant from the most recent command. The most recent command is not listed.
