The Presentation Graphics Facility (PGF) of the IBM licensed program. Graphical Data Display Manager (GDDM) helps you to draw business charts in a simple way, for displaying on a screen or for printing. An introduction to GDDM, including PGF, is given in the GDDM General Information book.

• The Interactive Chart Utility (ICU) that can be used interactively by anyone to create charts at the terminal. It can be started from:
  • The terminal. When the ICU is called from the terminal, it runs as a stand-alone utility; there is usually no need for DP specialists to be involved. Stand-alone use is described in the GDDM-PGF Interactive Chart Utility book.

  • An application program. When the ICU is called from an application program using the CSxxxx calls, all the functions are available to the programmer.

• The Presentation Graphics (PG) routines; these must be called from an application program. The PG routines (CHxxxx calls) are more flexible than the ICU, and allow you to create more complex charts, but they do not have any interactive facilities.

• The Vector Symbol Editor, which can be started from a terminal or from an application program.

Only the call to the Vector Symbol Editor will be discussed in this manual. For full details see the GDDM-PGF Vector Symbol Editor book. GDDM also provides an Image Symbol Editor, which is described in the GDDM Using the Image Symbol Editor book. You can use these editors to produce or modify symbols for annotating PGF charts.
