DEVICE 3 NAME COUNTER

DEVICE 3 NAME COUNTER (SET)

Set Subcommand

Specify whether device 3 output will generate each plot into a separate file.

Dataplot uses device 3 to maintain a copy of the most recent plot only (the default file name is "dppl2f.dat") in Postscript format. Dataplot automatically handles the opening and closing of device 3. The PP command uses the device 3 output to print the most recent plot from within a Dataplot session.

The SET DEVICE 3 NAME COUNTER command can be used to add a counter to the base file name each time the plot file is opened. That is, each plot will be saved in a different file name.

The counter is added to the name before the extension (i.e., the period in the file name). For the default name, the files will be called

dppl2f_1.dat
dppl2f_2.dat
....


You can use the SET IPL2NA command to specify the base file name. This is demonstrated in the Program example below.

SET DEVICE 3 NAME COUNTER <ON/OFF>

If you specify OFF (the default), the plot file will be overwritten each time a new plot is generated. If you specify ON, a counter value will be added to the plot file name so that each plot will be saved in a different file.
