Change

Changes the attributes of GQEs by calling the full screen menu driver (FSU by W. Drube).

Note: the default GKS attributes are changed by 'gks', to lauch a menu, or by 'set gks/attrName=value'.

Format:

SPECTRA> ch$*$ange [id]

Description:

A full screen menu is displayed. The user may change the attributes of a GQE. If the parameter is omitted, the first GQE is changed.

The values of the attributes are changed by over-typing them.

A change menu can be exited by PF4 or Ctrl-X.

The cursor is moved through the menu with these keypad keys: KP8 - up, KP2 - down, KP4 - left and KP6 - right. The values of toggle fields are selected with the right-arrow and left-arrow keys. An example for a toggle field is the colour (RED, GREEN, ...).

The meaning of the attributes is explained in the section about the SET command.

While the change menu is active, the user may call the locator. For SCANs it is used to set the viewport limits, for TAGs and TEXTs to mark the position. A viewport is specified by entering the lower left and upper right point.

The zoom command is possible for SCANs only. It prompts two points. They are used to change the window limits. The default window limits are restored by issuing an AUTOSCALE command or by specifying points, which are outside the viewport limits.

e.g.:

SPECTRA> change bpu1

Format:

SPECTRA> ch$*$ange/ct array_id

Description:

Changes an ARRAY colour table.

Format:

SPECTRA> ch$*$ange /digit$*$ize/bo$*$ard [id]

Description:

SPECTRA starts the digit-izing mode without entering the menu. Users can digitize their spectra with the DIGICAD board, which is in room 113 building 25b. The procedure is explained in sections 15.3.21ff.

/display

A display command is executed before SPECTRA enters the digitizing mode.

Format:

SPECTRA> ch$*$ange /digit$*$ize [id]

Description:

If the /digitize qualifier is entered without /board, SPECTRA expects input from a mouse. The left button adds a new point, ctrl-z ends the input.

/append

The digitized points are appended to the changed SCAN. This is only possible, if the current index is below the total number of points.

/display

A display command is executed before SPECTRA enters the digitizing mode.

Format:

SPECTRA> ch$*$ange /loc$*$ator id

Description:

The locator is immediately called.
