WinSATS allows the display of DIF (Data Interchange File) files in graphical form, and allows execution of SATS and user written data processing programs to manipulate them (eg FFT – Fast Fourier Transform ).The display consists of three types of window:-

1. The command window, (at the bottom), where text commands are entered.
2. The Menu bar, (at the top), where menu commands are executed using the mouse.
3. Graph window for displaying a DIF file.
4. A monitor window for displaying text and results

SATS can accept commands as ASCII text. These commands can be sent from:

• The keyboard
• A macro file
• The mouse
• Function keys

All commands are converted to ASCII text before execution, no matter where they originate.( This feature allows all commands to be logged to a macro file for later execution.)

Graph window commands control only the currently activegraph, as shown by the bright blue name bar in the active graph.  The current active graph can be changed using the “talk” command or by clicking the mouse in the graph window.

Macro and command line:

Two special characters, if found in a text command line, are expanded.  These can be included in text, macro files or menu commands.  These are:

•  # is substituted for the current default file name
• @f is substituted for a filename supplied by the user
• @d is substituted for a number supplied by the user via a dialog box
• @p is substituted for a point in the graph supplied by the user
• @z is substituted for an area in a graph supplied by the user
