Undoes one line of text entry, or undoes the last cut, copy, or
paste action.
In Base SAS windows, this command executes
the UNDO command. In SAS/GRAPH windows, WUNDO is invalid.
One execution of the WUNDO command undoes text entry for only one line
at a time. If you issue the WUNDO command again, the previous line of text
is undone.
If you use the CC command to copy and paste a block of text, and then
issue the WUNDO command, the block of text that you copied is deleted. If
you use the DD command to delete a block of text, and then issue the WUNDO
command, the block of text that you deleted is restored.
Note: The WUNDO
command cannot replace lines that the SUBMIT command removes. It cannot reverse
the effects of submitted SAS statements. ![[cautionend]](../../../../common/61991/HTML/default/images/cautend.gif)
