routes output to the file CUPLOT.PLT, instead of or in
addition to your terminal:
Command[ ]? PF !Plot to File
Preview on TTY[N]? Y !also view on terminal
Character to type to save a frame (CR for return) [D]? ,
closes any open plot file and routes output to your terminal.
Command[ ]? PT !Plot to Terminal
closes the file and sends it to the printer. A new version of
the output file is opened for the next plot, unless you turn off file
output. The default printer is your SYS$PRINT.
This only works if you have used the PF command.
