MPE V to MPE XL: Getting Started

Lesson 6:  DO and REDO 

You can reexecute any of the commands in your history stack by using the
familiar MPE V/E REDO command or the new MPE XL DO command.


The advantage of using DO instead of REDO is that DO immediately executes
the command after you press Return.  REDO requires that you press Return 
twice before the command reexecutes.

Same-Line Editing 

Both REDO and DO allow you to perform same-line editing before a command
is reexecuted.  That is, the syntax of these commands allows you to
specify editorial changes on the same line as the command itself.  REDO
also allows next-line editing in MPE XL, as it did in MPE V/E.

Refer to the MPE XL Commands Reference Manual (32650-90003), DO or REDO,
for an explanation of using the same-line editing feature.

Both DO and REDO may be used with or without specifying a command line
number from the history stack listing.

When a line number is not specified, the command most recently issued is
reexecuted.


Exercise 

9.   Display your command line history stack on your screen.  Use DO and
     REDO with and without specifying line numbers to reexecute any
     command in your command history.
