If you are operating in WINDOWS the [Print Scrn] key cannot be used to plot PAS graphs directly. There are 2 possible solutions:

1. You can save data in the graphs to disk by using the Save Data function key [F6] when the graph you want to plot is on the screen. Time series data are saved in a file labeled *.DAT (where * refers to your name for the data file). The original time series and simulated time series can be saved as *.DAT files. Autocorrelation data are saved as *.ACF and partial rate correlations as *.PCF. These files can be easily imported into a spreadsheet and then plotted using the spreadsheet graph function.
2. You can cut and paste the graphs into your word processor. When you want to cut and paste a graph while running PAS, press [Alt]+[Enter] to exit DOS and reenter WINDOWS. Press the Mark button and drag a box around the area you want to print. Press the copy button, open your word processor, and then paste the copied graphics into a document. You can then use the Print file option in the word processor to print the graph. To continue running PAS, use [Alt]+[Enter] to renter the DOS environment.
