Syntax: !ptrms l|t [r]Options can be space separated or grouped. At least one of l, t must be given. If l is given, the cell label markers will be moved to the default locations to the right of the parent cell. If t is given, all device terminals will be undefined and moved to the lower left of the parent cell. These actions can not be undone. If r is given, the operation is performed recursively on subcells. The characters c, d are equivalent to l, t. This command is used primarily for debugging purposes.
