Appendix D. Using GDFs in AFP Utilities IBM Advanced Function Printing Utilities for iSeries cannot create GDF in itself. Graphics data format (GDF) is a means of storing pictures. GDDM uses it internally, and also makes it available to application programs. It consists of a set of orders with similar meanings to the GDDM graphics call statements. In many cases there is a one-for-one mapping between GDF orders and GDDM call statements. You can create GDF easily by using Business Graphics Utility (BGU), and also by application programs. You can also create GDF on System/390. To use a System/390 GDF file, you must first convert the GDF file for use on the server. To convert the GDF file, use the GDF Bridge Utility of the Graphical Display and Query Facility (QGDF) Licensed Program. You can do conversions in either VM or in MVS/TSO. If the System/390 supports VM, type the following to start the GDF Bridge Utility and press Enter: EMGGDFB fn TOGDF |EXPAND| The entries in this procedure are as follows: If the System/390 supports MVS/TSO, type the following to start the GDF Bridge Utility and press Enter: EMGGDFB indsn outdsn member TOGDF |EXPAND| The entries in this procedure are as follows: The GDF file created by these procedures can then be migrated to the server for use by iSeries system. Note: GDFs created by System/390 GDDM releases subsequent to release 1.3 may not be supported by the system. fn The filename of a CMS file whose file type is ADMGDF. This file contains the ADMGDF object. TOGDF Indicates that the specified file is to be converted to a GDF file. EXPAND Specifies that vector symbols and arcs be expanded to lines. indsn The fully qualified name of the dataset that contains the ADMGDF object. outdsn The fully qualified name of the dataset that is to contain the GDF object. member The name of the member in the above datasets that contains the input/output. TOGDF Specifies that the input member is to be converted into a GDF file and stored in the output member. EXPAND Specifies that vector symbols and arcs be expanded to lines. 439
