Edit Menu Commands

The following !set keywords affect commands found in the Edit Menu.

MasterMenuLength
Value: integer 1-75.
This integer variable sets the length of the list of master cells retained in the Cell Placement Control panel. The default is 25, which may not be correct for some screen resolutions. It is not very useful if the pull-down menu extends off-screen.

The treatment of any path which is given with a cell to open in the Edit command can be altered with the next two variables.

NoReadExclusive
Value: boolean.
When a native cell name with a path is opened, the path is stripped from the cell name. If the path is not already in the search path, it is added. Ordinarily, the path is put in front of the search path for the duration of the read, so that subcells will be opened from the same directory. If this variable is set, the path is not necessarily moved to the front of the search path.

AddToBack
Value: boolean.
A path stripped from a given cell name in the Edit command is added to the back of the search path, rather than the front.

The behavior is described below for the various permutations:

NoReadExclusive unset
AddToBack unset
(default behavior)

The directory is added to the front of the search path during the read. The ``.'' element of the path, if it exists, is moved to the front after the read.

NoReadExclusive unset
AddToBack set

The directory is added to the front of the search path during the read. The ``.'' element of the path, if it exists, is moved to the front, and the directory is moved to the end after the read.

NoReadExclusive set
AddToBack unset

If the directory exists in the path, nothing is changed, otherwise the directory is added to the front. After the read, the ``.'' entry, if it exists, is moved to the front.

NoReadExclusive set
AddToBack set

If the directory exists in the path, nothing is changed, otherwise the directory is added to the end.

UndoListLength
Value: integer >= 0.
This variable sets the number of operations remembered in the Undo command. If not set, 25 operations are saved. If set to zero, the length is unlimited.

NoWireWidthMag
Value: boolean.
When set, the width of wires does not change when the wire undergoes magnification, in a Move, Copy, or Flatten operation.

CrsymOverwrite
Value: boolean.
When set, The Create Cell operation in the Edit Menu and the CreateSymbol script function can overwrite cells already in memory. This can be dangerous and is prevented by default.
