Allows a user to correct or modify the last IMAGE/SQL utility command. Syntax | |
Prerequisites | |
None. Description | |
Use this command to display the last IMAGE/SQL utility command entered. Use the
associated subcommands to correct
or change the displayed command. The REDO command applies only to the last
command entered and is available only in interactive mode. It is ignored with
a warning in batch mode. Subcommands | |
- D
deletes the character above the cursor. If D is repeated, each
character above each D is deleted. - I
inserts one or more characters immediately preceding the character above
the cursor. The D and I subcommands can be used in conjunction to delete
characters and then insert new characters. - R
replaces the characters above the cursor with new characters. If one
character is entered, the character above the cursor is replaced; if two
characters are entered, two characters (the character above the cursor and the
character to the right) are replaced; and so forth for additional characters. R is the
default subcommand and is only required when the character to be replaced is a
D, I, R, or U. - U
undoes the effect of the previous D, I, or R subcommand. Entering a U,
carriage return, then another U cancels all previous subcommands for this REDO
command and restores the line being corrected to its original form.
Once the command is corrected, enter a carriage return to issue
the command. Example | |
In the following example, the DISPLAY MAP command is corrected using the R subcommand.
>>DISPLAY MPA ⇐incorrect command entered
DISPLAY MPA
^
Syntax Error (ATCERR 32435).
>>REDO ⇐request to REDO command
DISPLAY MPA ⇐command displayed for corrections
RAP ⇐error replaced by correction
DISPLAY MAP ⇐corrected command displayed
