NAME

UNDO - Undo the last command

SYNOPSIS

UND <EOC>

DESCRIPTION

Reverses the last change to the current cell. UNDO reverses changes made with the ADD CHAnge COPy DELete MOVe SMAsh STRetch and WRAp commands.

Piglet makes a copy of the entire device definition list before any change and pushes it on an undo stack associated with each device. The depth of the stack is only limited by available memory.

When an UNDo is performed, the state prior to the UNDo is pushed on the REDo stack. UNDo and REDo can be performed in any order up to the limits of the saved information.

When the user finally makes a change to the cell with the any of the ADD, CHAnge, COPy, DELete, MOVe, SMAsh, STRetch, or WRAp commands, the contents of the REDo stack are cleared.

The information in both the UNDo and REDo stacks is lost when the editor is exited.

UNDO prints the depth of both the UNDO and REDo stacks.
