### CCDSHOW

Displays the value of the CCDPACK global parameters

#### Description:

This routine shows the current value of any CCDPACK global parameters.

ccdshow

#### Parameters:

Name of the CCDPACK logfile. If a null (!) value is given for this parameter, then no logfile will be written, regardless of the value of the LOGTO parameter.

If the logging system has been initialised using CCDSETUP, then the value specified there will be used. Otherwise, the default is "CCDPACK.LOG". [CCDPACK.LOG]

Every CCDPACK application has the ability to log its output for future reference as well as for display on the terminal. This parameter controls this process, and may be set to any unique abbreviation of the following:
• TERMINAL – Send output to the terminal only

• LOGFILE – Send output to the logfile only (see the LOGFILE parameter)

• BOTH – Send output to both the terminal and the logfile

• NEITHER – Produce no output at all

If the logging system has been initialised using CCDSETUP, then the value specified there will be used. Otherwise, the default is "BOTH". [BOTH]

Whether or not to save the values of the program parameters to a "restoration" file, which can later be used by CCDSETUP to restore the current values of the global parameters. If TRUE then you’ll need to specify the name of the file using the SAVEFILE parameter. [FALSE]
This parameter is only used if the SAVE parameters is TRUE. It allows you to give the name of the restoration file to be used when saving the program parameters. [CCDPACK_SETUP.DAT]
This parameter determines whether values keyed by Set Index are to be displayed. If CCDSETUP has been used to set up different global parameter values for different members of each Set, and this parameter is true, CCDSHOW will display the parameter values specific to each Set Index value as well as the current unkeyed value. [FALSE]

#### Examples:

ccdshow
This displays the current values of all the CCDPACK global parameters to the screen.
ccdshow save savefile=params.save
As well as displaying the global parameter values to the screen, this will also write them to a restoration file called "params.save". This file can be used at a later date to restore the current global parameter setup using CCDSETUP.
