Usage
REVIEW provides a means of going back and re-examining earlier portions of your terminal session. If the second argument is omitted (indicating end of range) a single line will be displayed. If no arguments are present, the entire terminal session will be listed. The uses are numerous:
Several commands use line numbers as arguments (EXEC, EDIT, DELETE, RETRY); you will probably need this procedure from time to time to locate commands you want to use again in some way.
If you get results that puzzle you, you may want to review the sequence of commands that produced them.
When using INPUT files, and directing the output to disk, you may want a reminder of what has just been executed before proceeding.
When recovering a session that was terminated abnormally, you will want to REVIEW the command stream before executing selected portions of it.
