DELete label ...
DELete ALL
Remove a line, or a group of lines, from the circuit description.
To delete a part, by label, enter the label. (Example `DEL R15'.) Wildcards `*' and `?' are allowed, in which case, all that match are deleted.
To delete the entire circuit, the entire word ALL must be entered. (Example `DEL ALL'.)
After deleting anything, there is usually no way to get it back, but if a fault had been applied (see fault command) restore may have surprising results.
