Programmed Symbols

Raster graphics are displayed with programmed symbols, which are downloaded to your workstation. Z and I Emulator for Windows supports up to six sets (PSA through PSF) of triple-plane and multiple-color programmed symbols.

Use programmed symbols as the graphics type when you intend to use host graphics applications originally written for the 3279G terminal.

Graphics applications use one or both of these methods to display graphical screens. Z and I Emulator for Windows allows you to enable or disable support for vector graphics and programmed symbols. Choose the type of support that our host applications require.

Note: If you use the OS2-Link (advanced) protocol under the GDDM program, do not choose programmed symbols. Also, do not choose programmed symbols when you use the OS2-Link protocol with other applications.
